| Abstract: | Stability failure for elastic-viscoelastic and plastic thin-walled rotator shells is analyzed.The relation equation between max stability failure strain and time is proposed for thin-walled cylindrical shell and spherical shell.The instantaneous internal pressures of stability failure for thin-walledratator shells can be calculated,and it can be applied in the calculation of practical engineering problems. |
