Compared to traditional, structural materials, composite materials offer designers much more performance and flexibility. However, these benefits come at the cost of increased material complexity and it is easy to overlook the challenges of producing high quality test data to support the needs of both design and materials development.
There are a wide range of mechanical test standards, developed specifically to test composite materials, plus auditing bodies such as Nadcap often strictly define further testing performance criteria e.g. specimen alignment.

Applying Experimental Results to the Shear Assessment Method for Solid Slab B...Eva Lantsoght
The combination of increased live loads and a more conservative shear capacity in the recently implemented Eurocodes, resulted in a large number of existing solid slab bridges in the Netherlands being shear-critical upon assessment. However, an enhancement of the shear capacity can occur in slabs under concentrated wheel loads due to transverse load redistribution. To quantify this effect, a comprehensive series of experiments on slabs and slabs strips under a concentrated load near to the support and under a combination of a concentrated and a line load was carried out. The experiments show the difference in behaviour for slabs, carrying the load in a two-dimensional way, as compared to beams in shear. The results from the laboratory research are used to develop recommendations, that are easily used in combination with the codes. These recommendations are implemented in a spreadsheet-based first-level assessment tool, the Quick Scan method. The assessment with this tool of selected cases of existing solid slab bridges shows that applying the experimental results into the assessment practice leads to an improved selection ability of the Quick Scan method.
"Fatigue testing of reinforced concrete beam instrumented with distributed op...TRUSS ITN
The use of fiber optic sensors on civil engineering structural health monitoring (SHM) applications have become quite popular for the past two decades. Within this type of sensors however, the study and use of Optical Backscatter Reflectometry (OBR) based Distributed Optical Fiber Sensors (DOFS) is relatively new. In this way, there is still some uncertainty that would allow the use of this technology in a more systematic and standardized way. Some of this uncertainty is related with the long-term reliability behavior of these sensors when applied on the monitoring of a structure under a large number of load cycles. In this way, the authors conducted a laboratory experiment where a reinforced concrete beam was instrumented with a DOFS that was adhered in a way to allow the measuring of strain on four different longitudinal segments on its bottom surface. A fatigue test was then conducted on this element where the inputted load range was the one expected on a standard highway bridge between its self-weight and the additional traffic load. Furthermore, each longitudinal segment of the DOFS was adhered to the concrete using a different adhesive in order to assess the optimal one in these conditions. The obtained data is then compared with strain gauges that are also instrumented on the concrete beam.
MODELING AND OPTIMIZATION OF COLD CRUCIBLE FURNACES FOR MELTING METALSFluxtrol Inc.
http://fluxtrol.com
Cold Crucible Furnaces (CCFs), widely used in multiple special applications of
melting metals, oxides, glasses and other materials [1], are essentially 3D devices and their
modeling is a complicated task. Multiple studies of CCFs have been made for their
optimization, but their electrical efficiency is still low; for metals approximately 25-30% and
even lower. Fluxtrol, Inc., made an extensive study of electromagnetic processes of CCFs
using computer simulation and laboratory tests. This study showed that electrical efficiency of
CCFs may be strongly improved by means of optimal design of the whole system with use of
magnetic flux controllers. Theoretical results had been confirmed by laboratory tests on
mockups and by industrial tests with real melting processes. The presentation contains a
description of the computer modeling procedure and major findings. They form a basis for
optimal design of electromagnetic systems of CCFs.
Stress and Durability Analysis of Threaded Connections in a Cast Aluminum Cyl...Altair
Bolted connections involve sharp notched components that are therefore sensitive to fatigue loading. In internal combustion engines, the journal bearings of the crankshaft are supported by bearing caps which are bolted to the cylinder block. These threaded connections are a fatigue concern as cracking may be experienced on dynamometer tests of new engines. The critical element of this application however is not the steel studs rather the threaded bolt holes in the cast engine block. While the nominal stress concept is applicable to the fatigue design of studs, a local stress approach has to be adopted to assess the fatigue strength of threaded bolt holes.
This paper addresses the fatigue design of this kind of threaded connection. Initially alternate methods of FE modeling and analysis of threaded joints by the local approach are critically examined. The parallel development of a simplified experimental test system involving a threaded hole in cast AlSi7 is described and used to generate baseline fatigue data under known loading conditions. The fatigue behavior of the experimental system is then analyzed on the basis of alternate FE models and post processing approaches. Finally, recommendations for the accurate and computationally efficient FE modeling and durability analysis of threaded connections in cast aluminum cylinder block are outlined.

On the Size-dependent Nonlinear Behavior of a Capacitive Rectangular Micro-pl...Kaveh Rashvand
This research deals with the effect of the intrinsic material length-scale parameter on the stability of a fully clamped rectangular micro-plate, which can be used as a RF MEMS resonator. A modified couple stress theory is utilized to model the micro-plate, considering the variable material length-scale parameter. The nonlinear governing equation of motion for static analysis is solved using the step-by-step linearization method (SSLM) and the static pull-in parameters, limiting the stable regions of capacitive resonators, are determined and compared to those obtained by the classical theory. The numerical results reveal that the intrinsic size dependence of materials leads to an increase in the pull-in voltage and natural frequency depending on the thickness of the micro-plate. Comparing these results to the experimental outcomes shows that utilizing the fixed material length-scale leads to unrealistic results in some manner.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Summary & Outlook
• Be aware of hourglassing
• The Swift hardening law can describe S700MC during
pure torsion
• Limited spiral necking was observed, probably due to
anisotropy
