The element siiffness matrix and the geometric stiffness matrix etc. are explicitly presented.
单元的刚度矩阵和几何刚度矩阵全部显式给出。

Method for computing the element restoring force, rather than the stiffness matrix, is the most important factor that determines the accuracy of a geometric nonlinear finite element problem.
几何非线性单元的精度主要决定于单元恢复力的计算方法，刚度矩阵对单元精度的影响很小。
