N2 - In this investigation, accurate numerical methods are presented for extracting intensity factors for cracked piezoelectric bodies. Two methods were used: displacement extrapolation and an area M-integral. Test problems were analyzed by means of the finite element method. The numerical procedure was based upon the derivation of the asymptotic expressions of stress, strain, electric flux density and electric fields for a crack parallel to the poling direction of the material for impermeable electrical boundary conditions. The numerical errors were relatively small (less than 0.7%) for both methods.
