1. CRL method ( constant rate of loading ) 2. CRE method (constant rate of elongation) 1. CRL method: The function of applied force is to extent the specimen until it eventually breaks down. Here the loading causes the elongation. By adding constant rate of water flow in a container which is attached with the …
