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

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