Legacy Kernel-Only Tensor Mechanics Action

Set up stress divergence kernels with coordinate system aware logic

warning:Deprecated Action

This legacy action will soon be deprecated in favor of the more inclusive TensorMechanics/MasterAction. See the description, example use, and parameters on the TensorMechanics/Master action system page.

Description

The LegacyTensorMechanicsAction is a convenience object that simplifies part of the tensor mechanics system setup. It adds StressDivergence Kernels (for the current coordinate system).

Constructed MooseObjects

The Legacy Tensor Mechanics Action is used to construct the kernels for the specified coordinate system.

Table 1: Correspondence Among Action Functionality and MooseObjects for the Tensor Mechanics Master Action

Functionality	Replaced Classes	Associated Parameters
Calculate stress divergence equilibrium for the given coordinate system	StressDivergenceTensors or StressDivergenceRZTensors or StressDivergenceRSphericalTensors	`displacements` : a string of the displacement field variables

Note that there are many variations for the calculation of the stress divergence. Review the theoretical introduction for the Stress Divergence. Pay particular attention to the setting of the use_displaced_mesh parameter discussion; this parameter depends on the strain formulation used in the simulation.

note:Use of the Tensor Mechanics MasterAction Recommended

We recommend that users employ the TensorMechanics/MasterAction whenever possible to ensure consistency between the test function gradients and the strain formulation selected.

# Patch Test

# This test is designed to compute constant xx, yy, zz, xy, yz, and zx
#  stress on a set of irregular hexes.  The mesh is composed of one
#  block with seven elements.  The elements form a unit cube with one
#  internal element.  There is a nodeset for each exterior node.

# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
#  The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
#  zx).  This gives a uniform strain/stress state for all six unique
#  tensor components.

# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
#  modulus is 5e5 (G=E/2/(1+nu)).  Therefore,
#
#  stress xx = 1e6 * 1e-6 = 1
#  stress yy = 1e6 * 2e-6 = 2
#  stress zz = 1e6 * 3e-6 = 3
#  stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
#             (2 * G   * gamma_xy / 2 = 2 * G * epsilon_xy)
#  stress yz = 2 * 5e5 * 2e-6 / 2 = 1
#  stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5
