柔度法推导刚度矩阵的探究
he Exploration of the Element Stiffness Matrix Derived from Flexibility Method
求解单元的刚度矩阵是有限元求解问题的必要过程，通常采用虚位移原理或是最小势能原理进行求解。本文以柔度法推导单元刚度矩阵，并以为扭转杆件为例求解其单元刚度矩阵。根据其应用原理可将其推广到其他形式单元刚度矩阵求解中。
It's necessary process for the finite element solution to solve the element stiffness matrix, which is solved by the principle of virtual displacement and the principle of minimum potential energy.In this paper the element stiffness matrix is derived from flexibility method, and the element stiffness matrix of the ttorsion bar is solved by Flexibility Method. The method can be also applied to solve other forms of the element stiffness matrix.
