Linear elasticity
=================

Overview
--------

This object implements a simple linear elastic stress update of the type

.. math::
   \bm{\sigma}_{n+1} = \mathbf{\mathfrak{C}}_{n+1} : \bm{\varepsilon}_{n+1}

where :math:`\mathbf{\mathfrak{C}}` is a temperature-dependent elasticity
tensor.
The model does not maintain any  history variables.

Parameters
