Interference Analysis Between Crack and General Inclusion in an Infinite Plate by Body Force Method

摘要

A continously embedded force doublet over the particular region can be regarded as the distributing eigen strain. This fact implies that many sorts of inelastic strain can be replaced by the force doublet. In the present paper, the force doublet is used to alter the local constitutive relationship. As a result, a method for analyzing the general inclusion problem in which the material properties of the inclusion are not only different from those of the matrix material but also can be even a function of spacial coordinate variables is proposed. The theoretical background of the present analysis is explained followed by some representative numerical results.
