Tensor Mechanics Module

The Tensor Mechanics module is a library of simulation tools that solve continuum mechanics problems. It provides a simple approach for implementing even advanced mechanics models:

  • Plug-n-play design enables users to encorporate the relevant physics for specific and varied simulations

  • Tensor implementation matches mathematical theory

  • Straight-forward procedure for adding new physics

The tensor mechanics system can be used to simulation both linear and finite strain mechanics, including Elasticity and Cosserat elasticity, Plasticity and micromechanics plasticity, Creep, and Damage due to cracking and property degradation

Explore the Capabilities and Start Modeling

The Tensor Mechanics module is used in a variety of pure mechanics simulations and in combined physics simulations with the Heat Transfer, Phase Field, Contact, Porous Flow, and XFEM modules; use the MOOSE combined module to perform simulations with multiple physics modules. The following figures show results from a few different simulations performed by tensor mechanics module users.

The tensor mechanics module is being developed by users at national laboratories and universities around the world. Contact the developers through the moose-users email list.

Developing New Tensor Mechanics Code

Consider becoming a developer yourself. The tensor mechanics module uses code syntax based on tensor forms. This approach allows the constitutive tensor equations to be implemented, clearly and concisely, in the same format as written in mathematical notation.
