Tensile Testing Machines. Tensile strength is the stress at which a material breaks or permanently deforms. There are three definitions of tensile strength, yield strength, ultimate strength and breaking strength. Tensile tests are usually carded out on wire, strip or machined samples with either circular or rectangular cross section. Test pieces are screwed into or gripped in jaws and stretched by moving the grips apart at a constant rate while measuring the load and the grip separation.
