conversion of motion

In view of these shortcomings,the rotational kinematic hardening theory is incorporated into modified Cambridge model,and the rotational hardening mechanism of ellipse yield surface is presented in the paper.

针对修正剑桥模型不能模拟土体剪胀性、应力路径转折时土体的应力应变特性以及应力引起的各向异性,将旋转运动硬化理论引入到修正剑桥模型中,给出了椭圆屈服面的旋转运动硬化机制,把等向硬化的修正剑桥模型扩展为旋转运动硬化模型。
