Common destructive tests mentioned are hardness tests and impact tests like the Charpy and Izod tests. Non-destructive testing methods discussed include dye penetration, magnetic particle, ultrasonic, and radiographic testing. Specific hardness tests covered are Rockwell, Brinell, Vickers, and Shore hardness tests.
The Rockwell hardness test was invented in 1914 by Hugh and Stanley Rockwell. It measures the hardness of materials by applying two loads with an indenter and measuring the depth of penetration. There are different Rockwell scales that use different loads and indenters depending on the material being tested, such as scales for metals, plastics, and surfaces. The test provides a simple hardness value measurement and is widely used for quality control and material testing in manufacturing.

This document discusses non-destructive testing (NDT) techniques for assessing concrete structures. It describes several NDT methods for evaluating concrete strength, locating rebar, detecting cracks, and assessing corrosion. Methods for strength assessment include rebound hammers, windsor probes, ultrasonic tests, and permeability tests. Corrosion can be evaluated using corrosion analyzers and resistivity meters.Rebar location and details can be obtained using profometers. Cracks are detected using microscopes, eddy current meters, and infrared cameras. NDT allows inspection without damaging structures and can estimate properties, monitor changes, and find defects in concrete.
This document discusses various types of textile testing instruments. It begins by explaining why quality testing is important for the textile industry in Bangladesh. It then lists the main reasons for textile testing such as checking raw materials and monitoring production. The document proceeds to describe different types of textile tests including mechanical, physical, chemical and product tests. It provides examples of specific instruments used such as the crimp rigidity tester, GSM cutters, and tensile testing machines. The document discusses the features and uses of several key textile testing instruments.
The document discusses different hardness testing methods. It describes Brinell hardness testing which uses a 10mm steel ball indenter under a load of 3000kg to test hardness. Vickers hardness testing uses a diamond pyramid indenter under loads ranging from 1-120kg. Rockwell hardness testing utilizes indentation depth under constant load to measure hardness using diamond cone or steel ball indenters under major loads of 60, 100, or 150kg. Microhardness testing uses Knoop indenters and low loads down to 25g to test small areas. Hardness is a measure of resistance to plastic deformation from indentation or abrasion.
Mechanical testing is used to determine material properties and detect defects. There are destructive and non-destructive tests. Destructive tests like tensile, impact and hardness testing damage samples, while non-destructive tests like dye penetrant, magnetic particle and ultrasonic inspection detect flaws without damage. Selection of test method depends on material, manufacturing process, component capability and cost considerations. Common mechanical properties tested include strength, hardness, ductility and toughness.
The Rockwell hardness test measures the hardness of materials using indenters under specific loads. It is a quick, inexpensive, and non-destructive test that can be used to test finished parts without damaging them. The test uses a diamond or steel ball indenter that makes an impression under an initial minor load and then a deeper impression under a major load. The hardness number is read from a dial and indicates the material's resistance to plastic deformation. The test is commonly used for quality control and finding tensile strength.
This document discusses non-destructive testing methods for concrete, including ultrasonic pulse velocity testing, rebound hammer testing, and cover meter testing. Ultrasonic pulse velocity testing uses transducers to measure the speed of ultrasonic pulses traveling through concrete and can indicate quality, uniformity, and strength. Rebound hammer testing measures surface hardness through a spring-controlled hammer, where higher rebound values indicate stronger concrete. Cover meters use electromagnetic principles to locate and measure rebar cover thickness in concrete. Non-destructive testing allows evaluation of concrete properties without damaging the structure.
The document discusses the field of mechanical engineering. It begins with defining engineering as using science to solve practical problems. It then lists some common engineering fields, with a focus on mechanical engineering. Mechanical engineering involves designing mechanical devices and systems, and utilizes concepts like thermodynamics, materials science, and fluid mechanics. The document outlines the basic foundations of mechanical engineering education, including studying properties of materials and performing tests like tensile, hardness, and fatigue testing. It also discusses thermodynamics and steam engines.

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
