Fundamental solutions and analysis of rectangular crack in 3D thermopiezoelectric media

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 piezoelectric medium and investigates a rectangular crack subjected to thermal loadings.
