External Material Examples, Structural Mechanics

Application ID: 32331

A new way to specify user-defined material models is included in COMSOL Multiphysics version 5.2.

For structural mechanics, you have the possibility to either completely define the material model in a domain, or to add an inelastic strain contribution to an elastic material.

The external material functions are coded in C, and compiled into a shared library. By programming a wrapper function in C, you can also call material functions written in another programming language.

This technology makes it possible to program your own material models and distribute such models as add-ons.

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