WebCompressive Strength Testing of Plastics. The compressive strength of a material is the force per unit area that it can withstand in compression. This is in contrast to the more commonly measured tensile strength. ASTM D695 is the standard test method in the USA. The figure below, from Mitsubishi Chemical Advanced Materials, shows the test ... WebMay 24, 2024 · The need to understand the effects of test artefacts is clearly demonstrated in the work of Patel et al. , who measured deformation from crosshead displacement during compression testing of cylindrical polyurethane foam specimens of lengths (L) 3.9 and 7.7 mm. It was found that the Young’s modulus of the short specimen (66 MPa) was less …
