**v9.01.109** SZLZ109 - Lemaitre damage during post-treatment
===============================================================

**Summary:**

The purpose of this test is to calculate the damage of LEMAITRE from a history of any multiaxial loading and the history of cumulative plastic deformation.

The damage :math:`D(t)` is calculated from the data of the stress tensor :math:`\sigma (t)` and the cumulative plastic formation :math:`p(t)` at all times :math:`{t}_{i}` (provided by the user). In addition, total damage :math:`D\mathrm{=}\underset{i\mathrm{=}1}{\overset{N}{\Sigma }}D({t}_{i})` is calculated.

The material characteristics :math:`E` (Young's modulus), :math:`\nu` (Poisson's ratio), and :math:`S` (material parameter) must depend on the temperature :math:`T` (:math:`T(t)` must therefore be provided by the user at the same times as :math:`\sigma (t)` and :math:`p(t)`).
