| 摘 要： | The plane problem of a crack terminating at the interface of a bimaterial piezoelectric,and loaded on its faces, is treated. The emphasis is placed on how to transform this problem into anon-homogeneous Hilbert problem. To make the derivation tractable, the concept of the axial conju-gate is introduced and related to the complex conjugate. The angle between the crack line and the inter-face may be arbitrary. Numerical results are given to illustrate the stress singularity at crack tip.

| Abstract: | The plane problem of a crack terminating at the interface of a bimaterial piezoelectric, and loaded on its faces, is treated. The emphasis is placed on how to transform this problem into a non-homogeneous Hilbert problem. To make the derivation tractable, the concept of the axial conju- gate is introduced and related to the complex conjugate. The angle between the crack line and the inter- face may be arbitrary. Numerical results are given to illustrate the stress singularity at crack tip. |
