| Abstract: | 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. |
