摘要
开发了二维边界元计算程序，用于计算焊接裂纹尖端应力强度因子．计算结果与经典解十分近似，平均相对误差不超过４％．该方法简便可靠，适于工程应用。
A computation program has been developed,using a two dimension boundary element method,for calculation of stress strength factor at the welding crackle tip. The calculation result is very similar to that from the classical method,and its relative average error is no more than 4%. The above method is easy,reliable and suitable for engineering use,which provides convenience for the research on the welded construction and the analysis of its lifetime.
