Piezoelectric Simulations - COMSOL Multiphysics
cdn.comsol.comanalysis of a piezoelectric actuator. A radially polarized piezoelectric tube is simulated, with two sets of boundary conditions. The first case illustrates the inverse piezoelectric effect, and the second case shows the direct piezoelectric effect. The model is based on a paper by S. M. Peelamedu et al. (Proceedings of the
