Lode parameter

Introduction of the Lode parameter (¯θ) as a new field available at Gauss points, which has been denoted as IF_LODE_PARAMETER. This variable is defined as: ¯θ=16θπ=12πarccos(J3¯σ)3 where θ is the Lode angle, J3 is the third invariant of the deviatoric stress tensor and ¯σ is the equivalent stress. The range of values of the Lode angle (θ) is [0,π/3]. The Lode paramater (¯θ), which values always lie in the interval [1,1], is a normalized version of the Lode angle (θ). This stress state variable will permit the definition of more advanced fracture criteria and damage models.

The respective documentation page has been updated: Doc Fields at Gauss Points.

Rupture Criterion Field

Do not forget to ignore this field if you are not considering fracture in your test.
For ALE: region.ignore(IF_RUPT_CRIT)
For Remeshing: cell.addFieldToIgnore(IF_RUPT_CRIT)

LemaitreChabocheContinuousDamage

It is now mandatory to include this parameter when using the isotropic version of the Lemaitre-Chaboche continuous damage model.
