[8.6.0] - 2024-05-29

Added

  • Add the isotropic-hyperelastic alexander(C1, C2, C2, gamma, k) material model formulation to be used in Hyperelastic().
  • Add the isotropic-hyperelastic Micro-Sphere miehe_goektepe_lulei(mu, N, U, p, q) material model formulation to be used in Hyperelastic().
  • Add the pseudo-elastic ogden_roxburgh(r, m, beta, material, **kwargs) material model formulation to be used in Hyperelastic().
  • Add an optional relative-residuals argument to ConstitutiveMaterial.optimize(relative=False).
  • Add a class-decorator constitutive_material(Msterial, name=None).
  • Add the Total-Lagrange MORPH material formulation implemented by the concept of representative directions morph_representative_directions(p) to be used in MaterialAD().
  • Add the Total-Lagrange (original) MORPH material formulation morph(p) to be used in Hyperelastic().
  • Add decorators @total_lagrange and @updated_lagrange for Total / Updated Lagrange material formulations to be used in MaterialAD.
  • Add the isotropic-hyperelastic anssari_benam_bucchi(mu, N) material model formulation to be used in Hyperelastic().
  • Add the isotropic-hyperelastic lopez_pamies(mu, alpha) material model formulation to be used in Hyperelastic().

Changed

  • Recfactor the constitution module.

Fixed

  • Fix plotting the keyword-arguments of a constitutive material ConstitutiveMaterial.plot(show_kwargs=True). For list-based material parameters of length 1, the brackets aren't shown now. E.g., this affects optimized material parameters.
  • Don't update the material parameters in-place in ConstitutiveMaterial.optimize().
  • Don't convert material parameter scalars to arrays in ConstitutiveMaterial.optimize().
