Hill Constants
Build and rotate the Hill Tensor. It can be used with other Hill plasticity and creep materials.
Description
The HillConstants material transforms the user specified hill constants from global co-ordinates to the material co-ordinates and stores them as a material property. It rotates the hill constants during the initial time step only. This class does not rotate the hill tensor during the simulation. The initial rotation is performed based of the user defined rotation angle parameters. The rotated Hill tensor is obtained as Stewart et al. (2011):
(1)
Here, is the transformed hill tensor, is the initial Hill tensor and is the transformation matrix. The transformation matrix is formed from the components of the total rotation matrix due to initial rotation and the orientation change due to large deformation.
Temperature dependency and large deformation kinematics
The Hill's tensor varies depending on temperature (due to texture) and depending on the material's rotation. To that effect, the user can create functions describing the evolution of the coefficients with temperature and provide it to the material, as follows:
[hill_constants]
type = HillConstants
# F G H L M N
hill_constants = "0.5 0.5 0.5 1.5 1.5 1.5"
function_names = 'F G H L M N'
temperature = temperature
[]
where six piecewise linear functions are created to define the material directional creep dependency with temperature.
In addition, the code accounts for finite strain rotation to update the Hill's tensor by default. For simple problems, the user can deactivate this feature by setting the input argument use_large_rotation to false. Updating of directional coefficients with finite strain rotation kinematics is stronly encouraged when the material Similarly, use of the transformed Hill's tensor would need to be disable in the creep model, i.e. the following input file's command line needs to be passed: use_transformation = false.
[hill_tensor]
type = HillConstants
# F G H L M N
hill_constants = "0.5 1.0 0.5 1.5 1.5 1.5"
use_large_rotation = true
[]
commentnote
Temperature coupling and large deformation updates have only been tested on creep models.
