Boundary effect on crack kinking in a piezoelectric strip with a central crack

In this paper, the boundary effect on crack kinking in a piezoelectric strip with a central crack vertical to the boundary under in-plane loadings has been investigated. By using integral transform techniques the present mixed boundary value problem was reduced to the solution of dual integral equations, which can be further reduced to solving Fredholm integral equations. Analytical solutions can be obtained when the width of the piezoelectric...
