✦ Synopsis

Aim of this study is to propose, to develop, to validate and to apply in intensive simulations an efficient nonhypersingular traction boundary integral equation method (BIEM) for the solution of anti-plane dynamic problems of piezoelectric solids with cracks or/and holes. The modelling approach is in the frame of continuum mechanics, wave propagation and linear fracture mechanics. The simulations reveal the dependence of the stress concentration factor (SCF) and the stress intensity factor (SIF) on the electromechanical coupling, on the type and characteristics of the dynamic load, on the material parameters and on the geometry of the defects.

Fracture behavior of piezoelectric solids under time-harmonic loading is numerically analyzed in this paper. A 2-D boundary element method (BEM) based on both displacement and traction boundary integral equations is presented. The time-harmonic Green's functions for the infinite plane are split into

Rational design of smart sensors and actuators that consist of piezoelectric solids requires a thorough understanding of the constitutive behavior of this material under mechanical and electrical loading. Domain switching is the cause of significant nonlinearity in the constitutive behavior of piezo
