# TensorMechanicsPlasticSimpleTester

The TensorMechanicsPlasticSimpleTester has not been documented, if you would like to contribute to MOOSE by writing documentation, please see Documenting MOOSE. The content contained on this page explains the typical documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.

Class that can be used for testing multi-surface plasticity models. Yield function = a*stress_yy + b*stress_zz + c*stress_xx + d*(stress_xy + stress_yx)/2 + e*(stress_xz + stress_zx)/2 + f*(stress_yz + stress_zy)/2 - strength

- enableTrueSet the enabled status of the MooseObject.
Default:True

C++ Type:bool

Description:Set the enabled status of the MooseObject.

- allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).
Default:False

C++ Type:bool

Description:In the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).
