双线性随动硬化材料的机械自紧身管残余应力
Residual Stress of Swage Autofrettage Gun Barrel with Kinematic Hardening Material
摘要
Abstract
To calculate the residual stresses of swage autofrettage gun barrel with kinematic hardening materi -al ,based on the theory of elasto-plastic mechanics and some assumptions , the formulas of plastic radius , reyeild radius ,and residual stresses of swage autofrettage gun barrel were successful derived .The theoretical value and the results of experiment were compared to verify the accuracy ,and the obtained theoretical value are good agreement with the results of experiment .关键词
