InteractionIntegralBenchmarkBC

!syntax description /BCs/InteractionIntegralBenchmarkBC

Description

This object provides a boundary condition that enforces a displacement field around a crack tip based on applied stress intensity factors KI, KII, and KIII. This is used to test the interaction integral capability.

Input Parameters

  • crack_front_definitionThe CrackFrontDefinition user object name

    C++ Type:UserObjectName

    Description:The CrackFrontDefinition user object name

    C++ Type:FunctionName

    Description:Function describing the Mode I stress intensity factor.

  • componentThe component of the displacement to apply BC on.

    C++ Type:MooseEnum

    Description:The component of the displacement to apply BC on.

  • poissons_ratioPoisson's ratio for the material.

    C++ Type:double

    Description:Poisson's ratio for the material.

  • KIII_functionFunction describing the Mode III stress intensity factor.

    C++ Type:FunctionName

    Description:Function describing the Mode III stress intensity factor.

  • variableThe name of the variable that this boundary condition applies to

    C++ Type:NonlinearVariableName

    Description:The name of the variable that this boundary condition applies to

  • KII_functionFunction describing the Mode II stress intensity factor.

    C++ Type:FunctionName

    Description:Function describing the Mode II stress intensity factor.

  • boundaryThe list of boundary IDs from the mesh where this boundary condition applies

    C++ Type:std::vector

    Description:The list of boundary IDs from the mesh where this boundary condition applies

  • youngs_modulusYoung's modulus of the material.

    C++ Type:double

    Description:Young's modulus of the material.

Required Parameters

  • crack_front_point_index0The index of the point on the crack front.

    Default:0

    C++ Type:unsigned int

    Description:The index of the point on the crack front.

  • save_inThe name of auxiliary variables to save this BC's residual contributions to. Everything about that variable must match everything about this variable (the type, what blocks it's on, etc.)

    C++ Type:std::vector

    Description:The name of auxiliary variables to save this BC's residual contributions to. Everything about that variable must match everything about this variable (the type, what blocks it's on, etc.)

  • diag_save_inThe name of auxiliary variables to save this BC's diagonal jacobian contributions to. Everything about that variable must match everything about this variable (the type, what blocks it's on, etc.)

    C++ Type:std::vector

    Description:The name of auxiliary variables to save this BC's diagonal jacobian contributions to. Everything about that variable must match everything about this variable (the type, what blocks it's on, etc.)

Optional Parameters

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

    C++ Type:std::vector

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

  • enableTrueSet the enabled status of the MooseObject.

    Default:True

    C++ Type:bool

    Description:Set the enabled status of the MooseObject.

  • seed0The seed for the master random number generator

    Default:0

    C++ Type:unsigned int

    Description:The seed for the master random number generator

  • implicitTrueDetermines whether this object is calculated using an implicit or explicit form

    Default:True

    C++ Type:bool

    Description:Determines whether this object is calculated using an implicit or explicit form

  • 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

    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.
