Due to their pronounced piezoelectric, dielectric and pyroelectric properties, thermo piezoelectric materials have being widely used in sensors, actuators, transducers and intelligent structures, etc. Considering thermal effects, this paper derives the fundamental solutions for uniformly distributed extended displacement discontinuities on rectangular elements in the isotropic plane of a 3D thermo...
A finite crack is studied in two-dimensional (2D) infinite piezoelectric medium with arbitrary electric poling direction in the present paper. A self-consistent method is employed to obtain the real crack opening and the electric field in the crack cavity under combined mechanical-electric loadings. The influences of poling direction and electric boundary conditions on fracture behaviors are investigated,...
In this paper, the Hybrid Extended Displacement Discontinuity-Charge Simulation Method (HEDD-CSM) [1] is used to study the mixed mode cracks in two-dimensional finite piezoelectric media under combined mechanical-electrical loadings. The HEDD-CSM combines the extended displacement discontinuity method (EDDM) and the charge simulation method (CSM). The solution for an electrically impermeable crack...
