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.

Overcoming Sheet Metal Testing Challenges

With a wide range of applications varying from white goods, automotive, and aerospace applications, sheet metals are often high in strength relative to their cross section area. It’s important to note that formability and ductility is also crucial, for which the common testing requirements are similar across applications. Explore the challenges in sheet metal testing.

A Case for Extensometry

A universal testing system very simply measures 2 things during a basic mechanical test: force (via the load cell) and displacement (via the crosshead encoder). To obtain a basic stress-strain curve, you might think that’s all you need. With the force measurement from the load cell, the cross-sectional area of the material can be used to calculate stress; and with the crosshead extension, the original distance between the grips or fixtures can be used to calculate strain throughout the test. How simple!

Question From a Customer: Air Bubbles in Extrudate

Q: We have an MF30 Melt Flow Indexer and started running tests on various polymers in our lab. Some of the samples have a lot of air bubbles in them. I believe this is contributing to inconsistencies in melt flow values. How do we minimize this?

A: There are a lot of reasons you could be seeing air bubbles in the filament sample. Ultimately, it comes down to keeping the testing and cleaning processes as consistent as possible.

Challenges of Rigorous Demands

The world of materials testing is changing

  • materials are getting stronger, stiffer, and lighter
  • test standards are becoming stricter
  • testing labs are asked to perform more complex analytical tests

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.
