DruckerPrager

Definition of plastic yield surface using Drucker-Prager with isotropic/kinematic hardening.

Fields

• yield_stress: String, default = ""

  Initial yield stress (or cohesion in the context of Drucker-Prager). (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)

• eta_1: String, default = ""

  Eta constant, which accompanies the pressure term in the yield surface. (required)

• eta_2: String, default = ""

  Eta constant, which accompanies the pressure term in the dissipation function. This needs to be input if non-associative plasticity is desired.

• xi: String, default = ""

  Xi constant, which accompanies the cohesion term in the yield surface. (required)
