摘　　要：论述了应用屈服条件确定残余应力的方法，并用Ｍｉｓｅｓ屈服条件建立了残余应力的计算公式，给出了确定残余应力的程序，对所提出的方法进行了实验验证．其结果表明，应用屈服条件法确定焊缝区最大残余应力值的方法具有实用和推广价值．The method of determining residual stress by yield condition is discussed, and thecomputational formula of residual stress is set up by Mises yield condition. The procedure offixing residual stress is given and the provided method has also been tested by experiments. Theexperimental results show that the method of defining the maximum residual stress ofwelding-line area has practical and spreading value.
