[6.0.0] - 2022-11-20

Added

  • Add project(mean=True) to project cell mean-values to mesh-points. Now project() supports Triangles and Tetrahedrons.
  • Add RegionBoundary.mesh_faces() for a mesh with face-cells on the selected boundary of a region.
  • Add pseudo-elastic material OgdenRoxburgh() which may be used with SolidBodyNearlyIncompressible().
  • Add umat = UserMaterial(stress, elasticity, nstatevars=0, **kwargs) with user-defined functions for the (first Piola-Kirchhoff) stress tensor P, statevars_new = umat.gradient([F, statevars], **kwargs) and the according fourth-order elasticity tensor A = umat.hessian([F, statevars], **kwargs) based on the deformation gradient.
  • Add UserMaterialStrain() for small-strain based user-defined material formulations with an umat-interface suitable for elastic-plastic frameworks.
  • Add LinearElasticPlasticIsotropicHardening() which is based on UserMaterialStrain() and constitution.linear_elastic_plastic_isotropic_hardening().
  • Add new math helpers math.ravel() and math.reshape().
  • Add optional axis argument on which the norm is evaluated math.norm(axis=None).

Changed

  • Unify material definition with methods for the stress P, statevars_new = umat.gradient([F, statevars]) and the elasticity tensor A = umat.hessian([F, statevars]). This breaks support for materials defined by matadi<=0.1.10.
  • Do not broadcast the (constant) elasticity tensor for linear-elastic materials as einsumt>=0.9.3 supports broadcasting along the parallel-executed dimension.
  • Change not-updating attribute of FieldContainer(fields).values to a method FieldContainer(fields).values() which returns the current field values.

Removed

  • Remove unused SolidBodyTensor() and SolidBodyTensorNearlyIncompressible().
  • Remove unused region argument of LinearElastic().hessian().
