Mechanical Models

This set of models are useful for composing multiphysics constitutive models in the presence of mechanical loads as well as by themselves when solving e.g. total-Lagrange or update-Lagrange formulations of solid mechanics.

Balance of Mass

Total Lagrange $\rho_R = J\rho$

Total Lagrange

$\rho_R\frac{\partial^2\mathbf{u}}{\partial t^2} = \nabla\cdot\mathbf{P} + \rho\mathbf{b}$
