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.

Instron has joined a new international group that is seeking to develop a best practice guide and test standards specifically for testing composites at high-strain rates.
As the automotive industry seeks ever-more-urgently to embrace composites, there is an increasing demand for testing composite material behavior at high-strain rates. The need for detailed data to inform crash simulation models first drove a renewed demand for equipment over the last 3 years, and now there is a need for international standardization in methodologies and data handling. The group’s aim is to facilitate generation and exchange of reliable and comparable test data in this highly challenging area.

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!

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.

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

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?
