How is tensile strength measured according to ASTM D638? Tensile strengthis the highest tensile stress that a specimen can reach during atensile test. This tensile strength can occur at a yield point, in which case it is referred to as tensile strength at the yield point. If the ...
Specified speed of testing varies depending on the specimen type and plastic rigidity. Note: Tensile properties determined include tensile stress (strength) at yield and at break, percentage elongation at yield or at break and modulus of elasticity. Also called ASTM method D638-84. See also ...
