Electrostrictive Disc

Application 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.

This model example illustrates applications of this type that would nominally be built using the following products:
