J0470204 Investigation on Singular Electric Displacement Fields at the Vertex of Interface in Piezoelectric Material Joints

Abstract

Singular electric displacement fields occur around the vertex of interface in piezoelectric material joints under loadings. Concentrated electric displacement is useful for engineering and singular electric displacement fields should be further investigated. In the present study, some characteristics of singular electric displacement fields in a piezoelectric material joint are investigated using 3-dimensional finite element analysis. Influences of loading conditions and geometric factors on singular electric displacement fields are discussed.
