Stress relaxation behavior of two turbine bolt steels was evaluated by the manual-controlled tensile stress relaxation test (TSRT) at high temperature. First, feasibility and the procedure of the manual-controlled tensile stress relaxation test (TSRT) is discussed and carried out on a general ...
Leff = effective length of bolt where tensile strength is applied (inches, m) E = Young's Modulus of Elasticity (psi, N/m2) A = tensile stress area of the bolt (square inches, m2) strain Stress Area The tensile stress area can be calculated as A = (π / 4) (d - 0.9743 / n...

Take the minimum yield in psi of the ASTM grade (see ourStrength Requirements by Grade Chartfor this value), multiplied by the stress area of the specific diameter (see ourThread Pitch Chart). This formula will give you the ultimate yield strength of that size and grade of bolt. Example:W...
reduction for holes. In case of a single angle member connected by one flange only, the net area shall be reduced by 10 %. For connections with one bolt only, the net area shall be reduced with 30 %. Allowable ultimate tensile stress is equal to 重音在紧张成员从净区域将被计算在减少...
Tensile strength is the maximum amount oftensile stressa material can withstand before it fails or breaks. It is a measure of the material's ability to resist deformation under tension or stretching forces. When high tensile loads are applied,ductileand brittle materials will approach failure. This...
当选择 已计算的抗拉应力区域(接头螺栓 PropertyManager) 时,程序将根据以下公式计算张力应力区域 (At),即螺栓螺纹截面的最小区域: At = [(d3 + d2) / 2)]2 * π /4 P = 螺距,即两个相邻螺纹线之间的轴向距离 n = 1 / P,每英寸 (ANSI) 或每毫米 (ISO) 的螺栓螺纹数 D = 名义螺栓柄直径 ...
當您選擇 計算的拉伸應力區域 (連接器螺栓 PropertyManager ) 時,程式會計算拉伸應力區域 ( At),這是螺栓螺紋部分的最小區域,根據公式: At = [(d3 + d2) / 2)]2 * π /4 P = 螺距,兩條相鄰螺紋之間的軸距 n = 1 / P,每英吋 (ANSI) 或公釐 (ISO) 的螺栓螺紋數 d = 名義栓身直徑 ISO ...
