Fracture Analysis of Particulate MEE Materials Using a Domain-Independent Interaction Integral Method
This paper first introduces an expanded tensor notation to express the basic relations of magneto-electro-elastic (MEE) media and then,derives a domain formulation of the interaction integral on the basis of the expanded tensor notation for computing the intensity factors (IFs).The present interaction integral does not require material properties to be differentiable and moreover,it is domain-independent for material interfaces,which may make the interaction integral to become one of the most promising techniques in analyzing the crack problems of MEE composites.Then,the numerical implementation of the interaction integral combined with the extended finite element method (XFEM) is introduced.Using this method,the crack problems of a particulate MEE plate are studied.
