Blog

Welcome to our new Instron Community Blog hosted by Instron. It is a compilation of the freshest, brightest, most-talented minds that Instron has to offer. The world of materials science is so vast and encompasses the broadest range of industries, materials, and challenges that no one person can possibly possess all the knowledge required to be the resident expert – or master of materials science. It takes a small army behind the scenes collaborating and sharing technical know-how, experiences, and ideas to present the most accurate, relevant, and timely information to you – our readers. 

We invite you to tell us who you are, share your stories and talk about your experiences. Join the Instron Community. 



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.
