摘要

The problem of smart laminated sandwich plates involves inter-dependent mechanical and electric fields. The mechanical/structural component is modelled by an elegant plate theory, which ensures inter-laminar shear stress continuity and satisfies stress free condition at the plate surfaces. Moreover, this theory contains unknowns at the reference plane only. The electric field is modelled by layer-wise theory to retain generality. The solution of the resulting problem is based on an element developed for this purpose. It satisfies C~1 continuity at element interfaces as demanded by the present plate theory. Numerical examples are solved to study the static response and its control.
