Finite Element Modeling of Partially Conductive Interfacial Crack in Piezoelectric Bimaterial
摘要
A plane strain state of an interface crack in a piezoelectric bimaterial under the action of electric loading parallel to the crack and mechanical loading orthogonal to it is analyzed using the finite element method (FEM). Both piezomaterials are polarized in the direction orthogonal to the crack faces. One part of the crack faces is electrically conductive, while the other is insulated. The fracture parameters of the crack are investigated and presented in graphical and tabular forms.
