Abstract
Singular electric displacement fields occur around the vertex of interface in a piezoelectric material joints under loadings. In the previous study, influence of load conditions on singular electric displacement fields in the piezoelectric material joints were investigated to apply for engineering. In this study, some characteristics of singular electric displacement fields in an outside domain of piezoelectric material joints were investigated by using 3-dimensional finite element analysis. Influences of loading conditions on singular electric displacement fields are discussed . Singular electric displacement fields in an outside domain of piezoelectric material joints occur around the vertex of interface in it under loadings. Singular electric displacement fields are infulenced by tme change of the stress to depend on a piezoelectric material joints.
