The following Properties make direct contributions to this Equation:
Other Properties make indirect contributions to the Equation through the Stress.

Description

The Force Balance equation is

M_{ij}\frac{\partial^{2}u_{j}}{\partial t^{2}}+C_{ij}\frac{\partial u_{j}}{% \partial t}+\nabla_{j}\cdot\sigma_{ij}-f_{i}=0

(6.120)

where $\bf u$ is the Displacement Field, $M$ is the mass density tensor, $\bf C$ is a damping coefficient, $\sigma$ is the stress tensor and $f$ is an external force density vector.
