ComputeLagrangianStrain
Compute strain in Cartesian coordinates.
Overview
The ComputeLagrangianStrain class calculates the basic kinematic quantities used by the new mechanics kernels mechanics kernels. The theory section on the new material system describes this class's role in greater detail, the following gives a brief description.
The class calculates the strain measures available for the constitutive models to use to define the stress update and the kinematic tenors required to setup the stress equilibrium problem for large deformation simulations. The stabilize_strain averages the volumetric/dilatational part of these strain measures using an stabilization approach to prevent locking of linear quad and hex elements for problems experiencing incompressible deformation. This class also adds in the extra deformation gradient imposed by the homogenization system.
The calculations differ somewhat between small and large deformation kinematic theory. The large_kinematics flag selects between the two theories. This flag should be consistent between the strain calculator and the kernels. The stabilize_strain flag determines if the calculator uses the stabilization Souza Neto et al. (1996).
Step-by-step the class:
Calculates the deformation gradient as for large deformations or for small deformations.
If
stabilize_strainis set, average the volumetric parts of the deformation gradient, as described in the stabilization documentation.If active, add the extra gradient to this displacement-based deformation gradient calculated in the ComputeLagrangianHomogenizedLagrangianStrain.
For large deformations only, calculate the kinematic tensors used to define the equilibrium problem in the right frame of reference in the kernels. For small deformations these measures are set to the identity.
Calculate the increment in the spatial velocity gradient: for large deformations and for small deformations.
Calculate the total strain increment as .
Sum up and subtract the eigenstrain increment over the step to fine the mechanical strain increment, .
Use the previous step values of total and mechanical strain to calculate the updated strain values: and .
commentnote
The strain calculator does not apply the eigenstrains to the deformation gradient, only the incremental and integrated strain measures.
schooltip
stabilize_strain should be set to true for problems using linear quad or hex elements where the material model produces incompressible or near-incompressible deformation. It should be set to false for higher order elements. The stabilization is ineffective for linear triangle or tet elements and these elements should not be used for incompressible or near-incompressible problems.
The calculator requires use_displaced_mesh=false and enforces this with an error.
Example Input File Syntax
The following example sets up the ComputeLagrangianStrain object for a large deformation problem without stabilization. For small deformations the only change would be large_kinematics=false.
