Wedging of piezoceramic materials.

The paper establishes a correspondence between the solutions for rectilinear cracks located in a piezoceramic plane at a right angle to the polarization axis and smoothly (no friction) opened with rigid wedges and the solutions for cracks in a purely elastic isotropic plane. This correspondence can be used to calculate the SIFs for cracks in a piezoceramic plane from the expressions for cracks in an elastic isotropic plane, without the need to solve the electroelastic problem. The following problems are solved as examples: opening of a semi-infinite crack with a semi-infinite rounded wedge, a truncated wedge, and a wedge of constant thickness; opening of two semi-infinite cracks with hyperbolic wedges and wedges of constant thickness [ABSTRACT FROM AUTHOR]
