The theory of linear piezoelectricity is applied to solve the plane strain electroelastic problem of an orthotropic piezoelectric ceramic strip with a central crack, which is situated symmetrically and oriented in a direction normal to the edges of the strip. Fourier transforms are used to reduce the problem to the solution of a pair of dual integral equations. They are then reduced to a Fredholm integral equation of the second kind. Numerical values on the stress intensity factor and the energy release rate for some piezoelectric ceramics are obtained, and the results are graphed to display the electroelastic interactions.
