【Abstract】 The paper gives the compatibility relation of internal force and moment, strain, displacement separately, and the formulations of finite element method in the transitional region for the improved Mindlin model of 2-D delamination. The postbuckling behaviors of composite laminated plates with circle and elliptical delamination are analyzed. The reliability and utility of the improved model are shown by these examples.更多还原
