Set Variables
Use the Set Variables subnode to Plasticity, Porous Plasticity, Soil Plasticity, Concrete, Rocks, or Elastoplastic Soil Material, in order to reset plasticity variables according to a Setting condition that you define. When the Setting condition is satisfied, the plasticity variables are reset to the specified values.
Set Variables
Enter the Setting condition. This is a Boolean expression that will determine when the plastic variables are reset.
From the Equivalent plastic strain list, select Do not set or User defined. The default User defined value is zero.
Specify the values for the components of the Plastic strain tensor. From the list, select Do not set or User defined. The default User defined values are zero for all components of the Plastic strain tensor.
Depending on the type of plasticity model, set additional plasticity variables.
Plasticity
If Armstrong–Frederick or Chaboche is selected from the Kinematic Hardening Model list, specify the values for the components of the Back strain tensor εb. From the Back strain tensor list, select Do not set or User defined. The default User defined values are zero for all components. The back stress tensor is then set to .
Porous Plasticity
From the Equivalent plastic strain in the matrix material list, select Do not set or User defined. The default User defined value is zero.
From the Porosity rate list, select Do not set or User defined. The default User defined value is zero.
Elastoplastic Soil Material
From the Consolidation pressure rate list, select Do not set or User defined. The default User defined value is zero.
When Extended Barcelona Basic is selected from the Material model list, specify the value for the Suction rate. From the Suction rate list, select Do not set or User defined. The default User defined value is zero.
When Hardening Soil Small Strain or Hardening Soil is selected from the Material model list, specify the value for the Plastic shear strain. From the Plastic shear strain list, select Do not set or User defined. The default User defined value is zero.
