ComputeLagrangianLinearElasticStress
Stress update based on the small (engineering) stress
Overview
This class implements the simple linear elastic model which returns the small stress as a linear function of the small strain. is an elasticity tensor calculated by a ComputeElasticityTensor object, with a name provided in the stress calculator input.
This model inherits from ComputeLagrangianObjectiveStress and so it will integrate an objective stress rate to provide a "hypoelastic" large deformation constitutive response based solely on the small strain model.
Example Input File Syntax
The key parameters are elasticity_tensor giving the name of the elasticity tensor and large_kinematics which controls whether the model uses the simple small stress, linear elastic update or integrates the model through an objective stress rate. The objective_rate parameters controls which objective rate is used.
The following example sets up a hypoelastic, large deformation model based on the truesdell rate using the default elastic tensor name ("elasticity_tensor").

[]Input Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:Yes
Description:Set the enabled status of the MooseObject.
- implicitTrueDetermines whether this object is calculated using an implicit or explicit form
Default:True
C++ Type:bool
Controllable:No
Description:Determines whether this object is calculated using an implicit or explicit form
- search_methodnearest_node_connected_sidesChoice of search algorithm. All options begin by finding the nearest node in the primary boundary to a query point in the secondary boundary. In the default nearest_node_connected_sides algorithm, primary boundary elements are searched iff that nearest node is one of their nodes. This is fast to determine via a pregenerated node-to-elem map and is robust on conforming meshes. In the optional all_proximate_sides algorithm, primary boundary elements are searched iff they touch that nearest node, even if they are not topologically connected to it. This is more CPU-intensive but is necessary for robustness on any boundary surfaces which has disconnections (such as Flex IGA meshes) or non-conformity (such as hanging nodes in adaptively h-refined meshes).
