Circumferential 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. WebCalculate the maximum allowable stress based on the modified Tresca criterion to maintain a design factor of safety of 2.5, if the yield strength is 38 MPa and μ = 0.09. 2. Calculate the size of the plastic zone based for a polymer with Young’s modulus (3.2 GPa), yield strength (25 MPa), and a critical fracture toughness (0.85 kJ/m 2). 3.
