压剪断裂属于弹性小变形几何非线性问题.本文应用于结构有限元法,把大量的迭代过程集中到包围裂纹的局部区域内,避免了对总体刚度矩阵的多次形成和求解,从而节省了机时和容量.
Compression-shear fault belongs to the geometrically nonlinear problem of small elastic deformation. This paper applies the structural finite element method and concentrates a large number of iterative processes on the local area surrounding the crack, avoiding the multiple formation and solution of the overall stiffness matrix, thus saving the Machine time and capacity.
