Joule Heating of a Microactuator

Application ID: 8493

This tutorial model of a two-hot-arm thermal actuator couples three different physics phenomena: electric current conduction, heat conduction with heat generation, and structural stresses and strains due to thermal expansion. In this model version, the geometry is parameterized so that the effect of varying the actuator's dimensions can be analyzed.

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