Electroelastic singularities in piezoelectric-elastic wedges and junctions

This paper concerns the determination of the order and angular variation of inplane singular electroelastic states due to material and geometric discontinuities in piezoelectric-elastic wedges and junctions. The mathematical complexity required for deriving the order and angular variation of singular electroelastic fields is avoided by an ad hoc developed one-dimensional finite element formulation. The polarization orientation of the piezoelectric material may be arbitrary. To illustrate the simplicity, accuracy and efficiency of the suggested procedure, the order and angular variation of singular electroelastic fields for practically useful piezoelectric-elastic wedges and junctions are computed and compared with the existing analytical solutions. © 2005 Published by Elsevier Ltd.link_to_subscribed_fulltex
