Generalized Plane Strain Action System
Set up the GeneralizedPlaneStrain environment
Description
This action sets up a generalized plane strain model. A detailed description of generalized plane strain model can be found in the formulation page.
GeneralizedPlaneStrain only works for 1D axisymmetric or 2D generalized plane strain cases. For 1D axisymmetric and 2D generalized plane strain cases in the x-y plane the number of displacement variables must be one or two displacements, respectively.
For 2D generalized plane strain cases in the x-z or y-z planes the number of displacement variables must be three.
Constructed MooseObjects
The GeneralizedPlaneStrain

Example Input Syntax
Subblocks
The subblocks of the GeneralizedPlaneStrain action are what triggers MOOSE objects to be built. If a generalized plane strain model is applied for the whole simulation domain, a single subblock should be used
[./GeneralizedPlaneStrain]
[./gps]
use_displaced_mesh = true
displacements = 'disp_x disp_y'
scalar_out_of_plane_strain = scalar_strain_zz
out_of_plane_pressure_function = traction_function
pressure_factor = 1e5

(moose/modules/solid_mechanics/test/tests/generalized_plane_strain/out_of_plane_pressure.i)if different mesh subdomain has different generalized plane strain model, multiple subblocks with subdomain restrictions can be used.
