| Abstract: | On the basis of elementary theory of elasto-plastic mechanics,the stress calculation method for elasto-plastic problems during the hydrostatic test of SRM case was summarized.FORTRAN program was compiled for 31Si2MnCrMoVE case.Compared with FE calculation results,the error of the method is less than 3.3%,which proves that the method is correct.In addition,according to three groups of measured test data,the calculation results of the method agree well with actual results,which further verifies effectiveness of the method. |
