TensorMechanicsPlasticWeakPlaneShear

under construction:Undocumented Class

The TensorMechanicsPlasticWeakPlaneShear 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.

Non-associative finite-strain weak-plane shear perfect plasticity. Here cohesion = 1, tan(phi) = 1 = tan(psi)

Input Parameters

  • internal_constraint_toleranceThe Newton-Raphson process is only deemed converged if the internal constraint is less than this.

    C++ Type:double

    Options:

    Description:The Newton-Raphson process is only deemed converged if the internal constraint is less than this.

  • yield_function_toleranceIf the yield function is less than this amount, the (stress, internal parameter) are deemed admissible.

    C++ Type:double

    Options:

    Description:If the yield function is less than this amount, the (stress, internal parameter) are deemed admissible.

  • smootherFor the 'hyperbolic' tip_scheme, the cone vertex at shear-stress = 0 will be smoothed by the given amount. For the 'cap' tip_scheme, additional smoothing will occur. Typical value is 0.1*cohesion

    C++ Type:double

    Options:

    Description:For the 'hyperbolic' tip_scheme, the cone vertex at shear-stress = 0 will be smoothed by the given amount. For the 'cap' tip_scheme, additional smoothing will occur. Typical value is 0.1*cohesion

  • tan_dilation_angleA TensorMechanicsHardening UserObject that defines hardening of the tan(dilation angle). Usually the dilation angle is not greater than the friction angle, and it is between 0 and 90deg.

    C++ Type:UserObjectName

    Options:

    Description:A TensorMechanicsHardening UserObject that defines hardening of the tan(dilation angle). Usually the dilation angle is not greater than the friction angle, and it is between 0 and 90deg.

  • cohesionA TensorMechanicsHardening UserObject that defines hardening of the cohesion. Physically the cohesion should not be negative.

    C++ Type:UserObjectName

    Options:

    Description:A TensorMechanicsHardening UserObject that defines hardening of the cohesion. Physically the cohesion should not be negative.

  • tan_friction_angleA TensorMechanicsHardening UserObject that defines hardening of tan(friction angle). Physically the friction angle should be between 0 and 90deg.

    C++ Type:UserObjectName

    Options:

    Description:A TensorMechanicsHardening UserObject that defines hardening of tan(friction angle). Physically the friction angle should be between 0 and 90deg.

Required Parameters

  • execute_onTIMESTEP_ENDThe list of flag(s) indicating when this object should be executed, the available options include NONE, INITIAL, LINEAR, NONLINEAR, TIMESTEP_END, TIMESTEP_BEGIN, FINAL, CUSTOM.

    Default:TIMESTEP_END

    C++ Type:ExecFlagEnum

    Options:NONE INITIAL LINEAR NONLINEAR TIMESTEP_END TIMESTEP_BEGIN FINAL CUSTOM

    Description:The list of flag(s) indicating when this object should be executed, the available options include NONE, INITIAL, LINEAR, NONLINEAR, TIMESTEP_END, TIMESTEP_BEGIN, FINAL, CUSTOM.

  • cap_start0For the 'cap' tip_scheme, smoothing is performed in the stress_zz > cap_start region

    Default:0

    C++ Type:double

    Options:

    Description:For the 'cap' tip_scheme, smoothing is performed in the stress_zz > cap_start region

  • cap_rate0For the 'cap' tip_scheme, this controls how quickly the cap degenerates to a hemisphere: small values mean a slow degeneration to a hemisphere (and zero means the 'cap' will be totally inactive). Typical value is 1/cohesion

    Default:0

    C++ Type:double

    Options:

    Description:For the 'cap' tip_scheme, this controls how quickly the cap degenerates to a hemisphere: small values mean a slow degeneration to a hemisphere (and zero means the 'cap' will be totally inactive). Typical value is 1/cohesion

  • tip_schemehyperbolicScheme by which the cone's tip will be smoothed.

    Default:hyperbolic

    C++ Type:MooseEnum

    Options:hyperbolic cap

    Description:Scheme by which the cone's tip will be smoothed.

Optional Parameters

  • control_tagsAdds user-defined labels for accessing object parameters via control logic.

    C++ Type:std::vector

    Options:

    Description:Adds user-defined labels for accessing object parameters via control logic.

  • enableTrueSet the enabled status of the MooseObject.

    Default:True

    C++ Type:bool

    Options:

    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

    Options:

    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).

  • use_displaced_meshFalseWhether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.

    Default:False

    C++ Type:bool

    Options:

    Description:Whether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.

  • force_preauxFalseForces the GeneralUserObject to be executed in PREAUX
