CALCULATING THE STRESS INTENSITY FACTORS OF AUTOFRETTAGED THICK WALLED CYLINDER DUE TO THE RESIDUAL STRESSES AND THERMAL STRESSES

    摘要
  • 摘要: 本文用权函数法计算了自增强残余应力和温度应力下厚壁筒的应力强度因子,导得了适用于各种材料、自增强度、裂纹深度、温度和尺寸的厚壁筒应力强度因子的计算公式,编制了计算程序,方便于工程应用。

     

    Abstract: In this paper, the stress intensity factors of thick-walled cylinder with a edge crack due to the autofrettaged residual stresses and thermal stresses are calculated using a weight function method. The formulas, suitable to various thick-walled cylinder with different material, overstrain, depth of crack and size, are developed. A program computer is worked out.
