几何非线性非保守系统弹性力学广义拟余能原理的应用

Application of generalized quasi complementary principles to geometric nonlinear non-conservative elasticity

应用几何非线性非保守系统弹性力学中的第一类两类变量广义拟余能原理,研究了一个典型的伴生力非保守系统的问题,并给出同时求解内力和变形两类变量的计算方法.

The research of generalized variational principles of nonlinear non-conservative elasticity is widely applied not only to FEM and other approximate calculating methods, but also to the accurate solution of nonlinear non-conservative elasticity conveniently. A typical non-conservative elasticity is studied by applying the generalized quasi-complementary variational principle of the first two kinds of variables in geometric nonlinear non-conservative elasticity, and the method of calculating the deformation and the internal force simultaneously was derived.
