Summary The stress singularities at the apex of a piezoelectric-conductor, -composite, or -piezoelectric junction are investigated under generalized plane deformation in this paper. The influencing parameters on the stress singularity order are the wedge angles, material properties, graphite fiber orientation, and piezoelectric poling direction. The singularities of decoupled inplane and antiplane electromechanical field s are investigated when piezoelectric materials are polarized in the ( x- y)-plane or along the z-axis. From the numerical results, the conditions of strongest and weakest singularity orders can be determined. [ABSTRACT FROM AUTHOR] |
