Materials Testing Applications

A look at the influence of sample preparation and tensile testing results.

Cuts made to prepare a sample for tensile testing are critical to the accuracy and quality of the results. Preparing a sample without jagged edges or nicks is vital to ensure accurate tensile results. Those imperfections will affect the ability to provide consistent tensile results for the physical properties of the specimen. The way a sample is handled can also have an impact on the tensile test results and should also be handled with care once cut.

For the purpose of demonstrating the importance of the sample cut, two preparation tools were evaluated – the JDC Precision Sample Cutter and the MTT 1” Strip Cutter.  Using a black plastic film, images shown are a 200-time magnification of the cuts made.
