Energy Release Rates for the Penny-Shaped Crack in a Linear Piezoelectric Solid
Source abstract
Abstract
A domain independent integral expression that is derived from the principle of virtual work and holds in curvilinear coordinates is used to derive the energy release rate for a penny-shaped crack in a linear piezoelectric solid. The virtual mechanical and electric displacement fields are chosen to allow variation of the crack tip position. Results for the energy release rate for a finite crack segment and point-wise show the effect of crack front curvature in a piezoelectric material.
