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。

In calculation, this method USES the same stiff matrix, and only to renew the load vectors, which means it will reflect the geometric nonlinear effect in the load vectors' iteration.

计算时该格式使用同一刚度矩阵，只需要不断更新荷载矢量，即在荷载矢量的迭代中反映几何非线性效应。
