Summary This paper deals with a smart composite disk for control of a thermoelastic deformation resulting from an unknown thermal load. The disk consists of a structural layer onto which piezoelectric sensor and actuator layers are bonded. First, an unknown heating temperature distribution is inferred from a sensor output. The thermoelastic displacement on the bottom free surface is then controlled...
Summary.The Laplace transform technique is utilized to obtain the exact solution for thermally-induced wave propagation in a circular piezoelectric plate. The temperature is assumed to satisfy the one-dimensional heat conduction equation that includes a relaxation time. Displacement and electric potential functions are introduced in order to solve the equations of motion and electrodynamics. Numerical...
