![]() ![]() As an example, you can create your own hyperelastic material by typing in an expression for the strain energy density as a function of the strains directly in the GUI. Many of the material models have a User Defined option.What do you do?Īs a matter of fact, there are three different ways in which you can define your own material: For instance, suppose you developed a specialized material model for a certain alloy and want to use it to solve a large structural mechanics boundary value problem in COMSOL Multiphysics. However, in some situations, the mechanical behavior of a material is not readily expressed in terms of an existing material model. These material models cover a vast majority of engineering problems within structural analysis. The Nonlinear Structural Materials Module, an add-on product to COMSOL Multiphysics®, provides a plethora of material models, including models for hyperelasticity, isotropic/kinematic hardening plasticity, viscoelasticity, creep, porous plasticity, soils, and more. Here, we demonstrate how to implement an external material model and then use it in an example analysis. The compiled code can then be called from the program using the External Material feature. ![]() The COMSOL Multiphysics® software gives you the option to program your own material model in C code. In structural mechanics, there may be situations when you want to implement your own material model. ![]()
