正交各向异性弹性力学的准凸重构核粒子法
Quasi-convex reproducing kernel particle method for orthotropic elasticity
摘要
Abstract
Combined with the Galerkin weak form of the control equations,the quasi-convex reproducing kernel approximation was applied to analysis orthotropic elasticity problems.The theoretical formulas were derived and the quasi-convex reproducing kernel particle method was established.The numerical accuracy and computational efficiency of the present method were compared and demonstrated by numerical examples.Numerical results show that compared with the element free Galerkin method and the traditional reproducing kernel particle method,the shape function of the proposed method has slightly better positivity with evidently improved numerical accuracy and satisfactory efficiency,the calculation time of the form function is 1.01 times o the traditional restructured kernel partied method.关键词
