该算法是利用变形梯度乘法分解获得弹性变形梯度演化方程,用增量迭代法积分该方程,显式更新各滑移上的临界分切剪应力。
Single crystal kinematics based on a multiplicative decomposition of the deformation gradient is used to obtain an evolution equation for the crystal elastic deformation gradient . The primary advantage of the algorithm is that it provides an implicit integration of elastic deformation gradient .
