有限元新型模式

New Form of Finite Element

摘要: 在三类变量函的余能广义变分原理和分片构造待解函数的基础上,建立了有限元新模式,求解由它形成的离散方程可同时获得位移,应变和应力函数值。这个新模式具有广泛的统一形式,便于用来编制大型通用程序系统。

Abstract: The new form of finite element is Established based on the generalized variational principle of complementary energy belonging to three independent argument function and unknown functions of piecewise construction. The displacement, strain and stress function are obtained by solving the discrete equations formed with the new form of the finite element facilities.
