| Abstract: | By Green's function on plane strain problems,we derive an explicit expression of Eshelby tensor for any weakly anisotropic shape inclusion.Using the Eshelby's expression,we give expressions of the stress fields and the strain fields inside and outside the inclusions.The goal of this paper is to use ADINA program and ANSYS program for FEM to simulate the stress fields and to check our theoretical expressions.The simulating method based on FEM can be used to verify the results of any shape Eshelby tensor.Our ... |
