含曲线裂纹的压电材料反平面应变问题
ANTI-PLANE STRAIN PROBLEMS OF CURVILINEAR CRACKS IN PIEZOELFCTRIC MATERIAL
摘要
Abstract
The analytic solution and the intensity factor of anti-plane strain problems of curvilinear cracks in piezoelectric materials are obtained by using the Faber series expansion of complex variable functions and solving Hilbert problem. The stress field is independent of the electric displacement loading, and the electric displacement field is independent of the stress loading while there only are stress and electric displacement loading on the boundary. The intensity factor of circular-arc cracks and elliptical cracks are obtained in some special cases.关键词
