An Electrostrictive Disc

Model ID: 12703

This tutorial shows how you can use the Electromechanics interface in COMSOL's MEMS Module to model Electrostriction. Electrostrictive materials (e.g. PMN-PT) exhibit nonlinear strain as a function of electric field.

This 2D axisymmetry model uses a parametric sweep of voltage to exhibit the nonlinear mechanical response to a linear variation in the electrical input. Note that the electrostrictive strain is unidirectional and is independent of the direction of the electric field.
