The Thermoelectromechanical J-Integral and the Thermal Permeability of Cracks
The J-integral for cracks in structures storing elastic, dielectric and thermal energies is derived from thermodynamical fundamentals. The FEM is applied to solve thermoelectrome- chanical boundary value problems, accounting for piezoelectric coupling, thermoelasticity and the pyroelectric effect. Examples demonstrate the influence of the thermal conductivity of cracks on the loading of the crack tip.
