Damping Of Composite Material Structures with Riveted JointsIJMER
Vibration and noise reduction are crucial in maintaining high performance level and
prolonging the useful life of machinery, automobiles, aerodynamic and spacecraft structures. It is
observed that damping in materials occur due to energy release due to micro-slips along frictional
interfaces and due to varying strain regions and interaction between the metals. But it was found
that the damping effect in metals is quite small that it can be neglected. Damping in metals is due to
the micro-slips along frictional interfaces. Composites, however, have better damping properties
than structural metals and cannot be neglected. Typically, the range of composite damping begins
where the best damped metal stops.In the present work, theoretical analysis was done on various
polymer matrix composite (glass fibre polyesters) with riveted joints by varying initial conditions.
Strain energy loss was calculated to calculate the damping in composites. Using FEA model, load
variation w.r.t time was observed and the strain energy loss calculated was utilised in finding the
material damping for Carbon fibre epoxy with riveted joints. Various simulations were performed in
ANSYS and these results were utilised to calculate the loss factor, Rayleigh‘s damping constants
and logarithmic decrement.

A composite material can be defined as a combination of two or more materials that
gives better properties than those of the individual components used alone. In contrast to
metallic alloys, each material retains its separate chemical, physical, and mechanical
properties. The two constituents are reinforcement and a matrix. The main advantages of
composite materials are their high strength and stiffness combined with low density when
compared to classical materials. Micromechanical approach is found to be more suitable for
the analysis of composite materials because it studies the volume proportions of the
constituents for the desired lamina stiffness and strength.
This book was originally prepared in 2012 and updated recently in 2015. The
objective of the present book is to present a complete and up ± to ± date coverage of
composite laminates properties and literature reviews through the usage of a wide
spectrum of old and recent bibliography.
The material presented in this book is intended to serve as an introduction and
literature review of composite laminated plates. In chapter one, the introduction was
presented from the points of view of fundamental definitions of fibrous composite
laminates and micromechanical properties of fibers and matrix materials. At the end
of the chapter the objectives of the present work were cited.
Chapter two contains a comprehensive literature review which includes
continuous developments in the theories of laminated plates. Also, a survey of
numerical techniques which could be used in the analysis of laminated plates.
Chapter three contains the conclusion of the present book. In this chapter the
important observations and findings were explained clearly.
The book is suitable as a review on theories of plates, numerical and / or
analytical techniques subjected to bending, buckling and vibration of laminated
plates.
Fabrication of composite materials by using short pineapple leaf fiber PALF :...ijiert bestjournal
Composite materials (also called composition materials or shorte ned to composites) are materials made from two or more constituent materials with significantly different physi cal or chemical properties,that when combined,produce a material with characteristics different from the i ndividual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons:common examples include materials which are stronger,lighter or less expensive when compared to traditional materials. In the last decades,the use of natural fibers as r einforcement in polymeric composites for technical application has been a research subject of scientist. Interest in natural fibers has increased worldwide due to their low cost,low density,hardness,higher fatigue endurance,good thermal and mechanical resistivity and to their environmental friendliness. The Asian markets have been using natural fibers for many years e.g.,jute is a common reinforcement in India. Natural fibers are increasingly used in automotive and packaging materials. India is an agricultural country and it is the main stay of Indian economy. Thousa nds of tons of different crops are produced but most of their wastes do not have any useful utilization. Agric ultural wastes include wheat husk,rice husk,and their straw,hemp fiber and shells of various dry fruits. These ag ricultural wastes can be used to prepare fiber reinforced polymer composites for commercial use.
Analysis Of Lpg Cylinder Using Composite MaterialsIOSR Journals
This paper aims is innovation of alternative materials of Liquid petroleum gas (LPG). So, the finite
element analysis of Liquefied Petroleum Gas (LPG) cylinders made of Steel and Fiber Reinforced Plastic (FRP)
composites has been carried out. Finite element analysis of composite cylinder subjected to internal pressure is
performed. Layered shell element of a versatile FE analysis package ANSYS (version 11.0) has been used to
model the shell with FRP composites.
A number of cases are considered to study the stresses and deformations due to pressure loading inside the
cylinder. First, the results of stresses and deformation for steel cylinders are compared with the analytical
solution available in literature in order to validate the model and the software. The weight savings are also
presented for steel, Glass Fiber Reinforced Plastic (GFRP) composites LPG cylinders. Variations of stresses
and deformations throughout the cylinder made of steel and GFRP are studied.
Composites are engineered materials made from two or more constituents with different physical or chemical
properties, which remain separate and distinct within the finished structure. A fiber is a material, which is made into
a long filament with diameter generally in the order of 10 microns. The aspect ratio of length to diameter can be
ranging from thousands to infinity in continuous fibers. Increasing worldwide environmental awareness is
encouraging scientific research into the development of cheaper, more environmentally friendly and more
sustainable construction and packing materials. For environment concern on synthetic fiber (such as glass, carbon,
ceramic gibers etc) natural fibers (such as flax, hemp, jute, kenai) etc are widely used. Industrial hemp fiber is one
of the strongest of the natural fibers available and possesses benefits such as low cost and low production energy
requirements. The primary objective of this research is to fabricate the natural fiber composites with suitable
processing/manufacturing methods and to examine the mechanical properties when subjected to Tension, Bending
and to compare & contrast the results with the available literature. In this research work, hemp fiber reinforced
Epoxy matrix composites have been developed by hand layup method with varying process parameters, such as
coupling agent(with and without compatibilizers) and different fiber percentages (10%,20% and 30% by weight).
The developed composites were then characterized by tensile test and flexural testing. Results show that the tensile
strength and flexural properties increases with the increase in fiber percentage. However after a certain percentage
the tensile strength decreases again. Compared to untreated hemp fiber, no significant changes in the tensile strength
have been observed for treated hemp fiber reinforcement. The flexural strength / modulus of the composite were
higher compared to pure epoxy for all filler/fiber loadings.

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!
