摘要: 压电介质的损伤与断裂力学是现代固体力学的重要课题.本文简要地综述了压电介质损伤与断裂力学研究的现状,集中讨论了:(1)裂纹面电边界条件的不同模型及其求解的结果;(2)宏观连续力学与细观力学用于压电介质的损伤与断裂的静力学分析;(3)压电介质动态断裂分析的某些新结果.文末,指出了今后在压电介质损伤与断裂研究的某些有吸引力的研究方向Abstract: Damage and fracture mechanics of the piezoelectric medium is a very important branch of solid mechanics. First, the current research on the damage and fracture mechanics of piezoelectric materials is reviewed. Three topics are addressed: (1) different formulation of the electric boundary of defect and its effect on the mechanical behaviour of the damage and fracture of the piezoelectric medium; (2) static analys for the fracture by using the continuum mechanics and mesomechanics approach; (3) some new res...
