TotalLagrangianStressDivergence
Enforce equilibrium with a total Lagrangian formulation in Cartesian coordinates.
Description
The TotalLagrangianStressDivergence kernel calculates the stress equilibrium residual in the reference configuration using the pk1_stress (the 1st Piola-Kirchhoff stress). This kernel provides the residual for Cartesian coordinates and the user needs to add one kernel for each dimension of the problem. Alternatively, the SolidMechanics/QuasiStatic simplifies the process of adding the required kernels and setting up the input parameters.
Residual, Jacobian, and stabilization
For large deformation kinematics the kernel applies the residual giving the weak form of the divergence of the 1st Piola Kirchhoff stress with respect to the reference coordinates with the corresponding Jacobian where is the first Piola-Kirchhoff stress, are the test function gradients (with respect to the reference coordinates) and with the discrete (nodal) displacements. For the unstabilized case with the trial function gradients with respect to the reference coordinates.
The residual and Jacobian degenerate to and for the small deformation case, with the small stress, with the small strain and for the unstabilized case. The large_kinematics flag controls the kinematic theory.
The constitutive model needs to provide the first Piola-Kirchhoff stress and the derivative of that stress with respect to the deformation gradient. However, the material system provides a common interface to define the constitutive model with any stress and strain measures that are convenient, translating the user-defined stress and Jacobian to the correct form automatically.
The kernel is compatible with the modification of the strains to stabilize the problem for incompressible or nearly incompressible deformation. This form of stabilization does not modify the residual equation, though the modified strain does change the constitutive model stress update. The strain modification does affect the Jacobian by altering the definition of the gradient tensors. With the modified strains applied these become for small deformations with and for large deformations with and the average deformation gradient, defined in the stabilization system documentation.
