| Abstract: | Based on the theory of elasticity-plasticity, the computing formulas of plastic failure pressure and its probability of the solid rocket motor case which made by the high strength steel have been derived. The relationship between stress and straln of the high strength steel presents power function form.Based on the fracture mechanics, the formulas of brittle failure pressure and its probability of the motor case, whose surface has cracks, have been derived too. |
