混合元分裂因子的取值与层合板静力学问题分析
The value of mixed elements splitting factor and analysis of static problems in laminated plates
摘要
Abstract
Compared to the traditional mixed variational principles,the superiority of generalized mixed varia-tional principles with splitting factors is very obvious.At present,the selection of splitting factor values in general-ized mixed models is an open problem.Based on the theory of strain energy equal to complementary energy and strain energy and complementary energy equal to half of the mixed energy in the linear elastic problem,an error a-nalysis method for selecting splitting factors is proposed.This method provides a new approach for obtaining appro-priate splitting factors for the compatible generalized mixed elements.Numerical example analyses show that the splitting factor value of the compatible mixed element obtained by the method in this paper can adapt to the 3D com-posite laminated plate problem,and more accurate numerical results can be obtained under the same mesh model.关键词
