CSMm 2.5.Constitutive Laws
The constitutive law class is a core class of kratos. Located in kratos/kratos/includes/constitutive_law.h.
ConstitutiveLaw derives from Flags
The flags that are in use right now are only used as options for the computation of the material response.
Current Avaliable Flags:
StrainMeasure_Infinitesimal, Infinitesimal strain measure related to small displacements
StrainMeasure_GreenLagrange, Green-Lagrange strain measure related to the reference configuration
StrainMeasure_Almansi, Almansi strain measure related to the current configuration
StrainMeasure_Hencky_Material, Hencky strain measure expressed in the reference configuration
StrainMeasure_Hencky_Spatial, Hencky strain measure expressed in the current configuration
StressMeasure_PK1, First Piola-Kirchhoff stress related to the reference configuration non-symmetric
StressMeasure_PK2, Second Piola-Kirchhoff stress related to the reference configuration
StressMeasure_Kirchhoff, Kirchhoff stress related to the current configuration
StressMeasure_Cauchy, Cauchy stress related to the current configuration
