| Abstract: |
| The problem involving an edge-crack in a rectangular material under inplane electrical loading and antiplane mechanical shear loading is analyzed,a general solution of electro-mechanical field is obtained,which satisfies both Laplace equation and the boundary conditions of the crack sufraces,the unknown constant can be solved by the boundary condition around the rectangular piezoelectric body.At last,the boundary collocation method is used to calculate the energy release rate.It is shown that the method of semi-analytical and semi-numeral is simple, and widely applicable. |
