摘要
本文利用Chen和Shioya给出的在横观各向同性压电无限体内币形裂纹上下表面作用对称法向点力和点电荷情形下的解,结合压电材料之功的互等定理,用初等函数的形式给出了在压电无限体中任意一点作用任意点力和点电荷情形下币形裂纹的张开位移。并对PZT-4压电陶瓷和对应的非压电材料作了计算分析。
Based on the reciprocity theorem of piezoelectric media and the solution [1] of a penny-shaped crack in a transversely isotropic piezoelectric body subjected to the symmetric point charges and normal point forces, the expression of opening displacement of a penny-shaped crack in a transversely isotropic piezoelectric body subjected to the arbitarily located point forces and point charges were obtained in terms of elementary functions. At last, graphics are shown for PZT-4 and the corresponding non-piezoelectric materials.
