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:



 STRAIN MEASURES:

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

true strain:

StrainMeasure_Hencky_Material, Hencky strain measure expressed in the reference configuration

StrainMeasure_Hencky_Spatial, Hencky strain measure expressed in the current configuration


 STRESS MEASURES:

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
