Size effect on crack kinking in a piezoelectric strip under impact loading

An impermeable crack in a piezoelectric strip under in-plane mechanical and electric impact loading is considered. The crack is located at an arbitrary position and parallel to the surfaces of the piezoelectric strip. Fourier and Laplace transforms are applied to reduce the mixed-mode crack problem (modes I and II) to a system of singular integral equations. Full singular fields around the crack tip are obtained asymptotically in an explicit...
