Introducing the Porous Media Flow Module
From multiphase transport and non-Darcian flow to local thermal equilibrium and nonequilibrium, we discuss the advanced porous media flow modeling you can do with the Porous Media Flow Module.
How to Model Large-Strain Viscoelasticity in COMSOL Multiphysics®
Learn how to model large-strain viscoelastic deformation, a common behavior exhibited by polymers and biological tissues, in COMSOL Multiphysics®.
Accessing External Material Models for Structural Mechanics
In COMSOL Multiphysics®, you can access not only material models derived from external libraries but also material functions programmed by yourself. We demonstrate with concrete damage model.
Introducing Nonlinear Elastic Materials
Nonlinear elastic materials present nonlinear stress-strain relationships even at infinitesimal strains — as opposed to hyperelastic materials, where stress-strain curves become significantly nonlinear at moderate to large strains. Important materials of this class are Ramberg-Osgood for modeling metals and other ductile materials and nonlinear soils models, such as the Duncan-Chang model.
