MechanicalFemPhysics

Introduction

The Mechanical FEM physics plugin is responsible for providing an implementation for the equilibrium equation that can be used together with the Fem process to solve static problems in 2D, axisymmetric and 3D. The main equation solved by this physics is:

\[ \nabla \sigma + b = 0 \]

where:

• \(\sigma\) is the current stress vector
• \(b\) is the body forces

The Mechanical FEM physics plugin supports the following formulations:

• Solid continuum element
• Interface elements
• Composite Elements

Plugin Options

A reference manual documenting the set of state variables and material properties expected by the plugin, along with all of its supported configuration and result options can be found in Mechanical Fem Plugin options.
