Through constitution of PM space density function, the stress-strain state equation for saturated rocks has been defined and the hysteresis loops of axial stress-radial stress has been simulated.
通过构筑PM空间密度函数,求出饱和巖石的应力—应变状态方程,并模拟了其轴向应变—径向应变滞后回线。
Based on lots of tube bending experiments, the stress-strain state along the tangential direction of bending line and the direction of the wall thickness is analyzed.
