| 摘 要： | 该文用权函数法求解出由温度应力引起的厚壁壳体内表面裂纹的应力强度因子，推导了计算应力强度因子的权函数公式，这些公式可用于不同材料，温度，裂纹深度和尺寸的壁厚壳体在不同温度下应力强度因子的计算，同时还得到了一些温度应力强度因子随裂纹深度变化的规律，这些规律对厚壁壳体的设计及工程应用有一定的参考价值。

| Abstract: | Weight function is approached to stress intensity factors for half ellipitical surface cracks in the temperature stress.The weight function formula are worked out and can be used for all kinds of materials, temperatures,cracks and different thick walled shells to compute the stress intensity factors. At the same time, the rule of the stress intensity factors in the temperature stress of thick wall shells with the change of crack depths is obtained.The rule is of some reference value to the design and engineering of the thick wall shells. |
