Abstract

A numerical method for actuating performance evaluation of LIPCA proposed using a finite element method. Fully coupled formulations for piezo-electric materials were introduced and 3-dimensional eight-node incompatible element was used. After verifying the developed code with typical examples, the center deflections of LIPCA were calculated and compared with the experimental result, which were in fairly agreement.
