DoublePowerLaw

Definition of creep behavior using a double power law.

Fields

• plasticity_coupling: Bool, default = false

  Coupling with plasticity.

• creep_stress: String, default = ""

  Initial stress at which creep starts to develop.

• creep_tangent_modulus: String, default = ""

  Hardening modulus which increases creep stress with respect to creep strain (linear parameter).

• flow_direction: CreepFlowDirection, default = Deviatoric

  Flow direction of the creep strain.

• parameter_A1: String, default = ""

  First linear constant. (required)

• parameter_n1: String, default = ""
