MohrCoulomb

Definition of plastic yield surface using Mohr-Coulomb with isotropic/kinematic hardening.

Fields

• yield_stress: String, default = ""

  Initial yield stress (or cohesion in the context of Mohr-Coulomb). (required)

• isotropic_hardening: String, default = ""

  Isotropic hardening parameter. (required)

• kinematic_hardening: String, default = ""

  Kinematic hardening parameter. (required)

• isotropic_hardening_function: String, default = ""

  Function name used to define isotropic strain hardening. (required)

• kinematic_hardening_function: String, default = ""

  Function name used to define kinematic strain hardening. (required)

• phi: String, default = ""

  Frictional angle (in radians). (required)

• psi: String, default = ""

  Dilatancy angle (in radians). This needs to be input if non-associative plasticity is desired.
