Note: 30% or 50% of the stress modulus, tensile test is the elongation of 30% or 50%, the elongation rate - stress intensity curve showing the tensile strength resins, such as the spacing of 60mm test fixture , then 30% of the value of the stress model, is stretched to 18mm when the stress intensity; the same value as 50% of the stress model, is stretched to 30mm when the stress intensity.
