Slow strain rate tensile testing

Webb1 mars 1992 · Briefly, the SSR technique involves the slow straining of a specimen of the alloy of interest in a possible cracking environment. Typically, a strain rate of the order of 10?6 s?1 is used, which is about four orders of magnitude slower than that used in a standard tensile test. WebbTensile testing is an important materials test to select a specific material for an application, for quality control, and to predict how a material will react to varying forces.” Expedited Tensile Testing Services Are Available- Contact Us Today at 724-537-3131 Customized Test Setups
