WebThe value of yield stress is generally lower than the ultimate stress. The ultimate stress is higher than the yield stress. 4] The yield stress is used as a criterion for the design of ductile material. Ultimate stress is the criteria for the design of brittle material. 5] The brittle material doesn’t have yield stress. WebThe maximum principal stress failure theory states that when any one of the three mutually perpendicular principal stresses exceeds the yield strength of the material at temperature, a failure will occur. Of the three principal stresses in piping induced by internal pressure, the circumferential will normally be the governing stress. get rid of green checkmarks on icons
