Higher Order Zig-zag Piezoelectric Plate Theory Under Thermo-electric-mechanical Loads

열-전기-기계 하중 하에서의 고차 지그재그 판이론

A decoupled thermo-piezoelectric-mechanical model of composite laminates with surface bonded piezoelectric actuators, subjected to externally applied load, temperature change load, electric field load is developed. The governing differential equations are obtained by applying the principle of free energy and variational techniques. A higher order zigzag theory displacement field is employed to accurately capture the transverse shear and normal effects in laminated composite plates of arbitrary thickness.
