Determinations of Mixed-Mode Stress Intensify Factor for Cracks under Thermal Shock with Thermal Weight Function Method
【摘要】 采用热权函数法对热冲击下复合型裂纹的应力强度因子进行求解,给出了热权函数法计算复合型裂纹应力强度因子的有限元格式。对典型例题进行计算,证明热权函数法具有较高的计算效率与满意的工程精度。
【Abstract】 Stress intensify factors (SIF) of mixed-mode crack under thermal shock was determined with thermal weight function (TWF) method. Formulations of finite element implementation of TWF method were given for mixed-mode crack.. Example shows that the scheme is of very high efficiency and of good accuracy.
