【Abstract】 The stress function and induction function in the form of polynomials as well as the fundamental solution of a functionally gradient piezoelectric cantilever are obtained. As an application of the general solution in engineering, the tip deflection and blocking force of a functionally gradient piezoelectric cantilever actuator is studied. Solutions of the cantilever under different loading conditions can be obtained based on this fundamental solution.更多还原
