Testing Metals to ASTM E8 with an Automatic Contacting Extensometer

The ASTM E8 standard describes tensile testing methods to determine yield strength, yield point elongation, tensile strength, elongation, and reduction of area for metals. It applies to metallic materials in any form: sheet, plate, wire, rod, bar, pipe, and tube.

Energy-Controlled Impulse Testing of Shoes

Shoe and shoe material manufacturers alike must be able to prove that their products will withstand a substantial amount of wear and tear before releasing them to market. Useful in this analysis is the ability to simulate the impact of a runner on the sole of a shoe. During a typical gait cycle, these impacts can be higher than 3kN for an adult runner. In addition to controlling the load with which an impact is generated, researchers may also wish to control the energy which is generated as a result of the impact. A testing machine, which can successfully cater to these requirements, must be able to create and maintain a repeatable impact of a certain energy over a prolonged number of cycles.

Question From a Customer: How to Report Strain at Break Following ASTM D638

Question: I am following ASTM D638-10, and my 'strain at break' results are nearly half of what other labs are reporting for the same material. What is wrong?

What is Digital Image Correlation (DIC) and How Can It Help Me?

Digital Image Correlation (DIC) is an analytical technique that compares images of a specimen’s surface during testing to generate full-field strain maps. This technology gives you more information than a traditional point-to-point extensometer or a strain gauge and allows you to see the complete story of the material’s behavior beyond the stress strain curve.

Challenges with Steel

The continual drive for improved safety and increased fuel efficiency within the automotive industry hasn't escaped anyone; the message is repeatedly broadcast via news outlets and advertised by auto manufactures themselves. The majority of new car models compete fiercely for the most impressive fuel efficiency (mpg or L/100km) figures in class. As auto manufactures strive for improved fuel economy, it is clear that material selection will continue to be an important factor in weight reduction.

Question from a Customer: What tup do I use on my 1,800 J (1,330 ft-lb) drop tower?

As a starting point for this response, the 1,800 J is the impact energy that your drop tower is capable of reaching. Selection of which tup to use does not have as much to do with the impact energy as it does with the way that the sample being hit reacts to the impact.

Carbon Fiber Hits the Road

By 2016, the US car industry will need to average 34.5 mpg and by 2025, cars will need to average 54.5 mpg. In order to meet these new requirements, manufacturers will have to implement a number of changes including new engines, technologies, and materials. Lightweight materials are one of the most important avenues to pursue because for every 10% reduction in weight, fuel efficiency is increased by 6–7%.

Poisson's Ratio Testing With A Biaxial Extensometer

Poisson’s Ratio has proven to be a challenging calculation for obtaining both repeatable and accurate results. To improve repeatability, we typically recommend grips that provide consistent clamping pressure, such as pneumatic side acting grips.
