根据炮钢材料在加载与卸载过程中的真实应力应变关系,应用弹塑性厚壁圆筒的一般理论,建立了考虑加载、卸载线性强化及鲍辛格效应的应力方程。最终给出了一种液压开端自紧身管的残余应力解析解。并以相应的残余应力测试实验证明,该解析解具有很高的精度。
According to the true stress-strain relationship during the loading and unloading process of gun steel, the stress equation considering the linear strengthening and Bauschinger effect is established by using the general theory of elastic-plastic thick-walled cylinder. Finally, an analytical solution of the residual stress of the self-tight tube is given. And the corresponding residual stress test experiments show that the analytical solution has a high accuracy.
