ADHeatConduction
Description
ADHeatConduction is the implementation of the heat diffusion equation in HeatConduction within the framework of automatic differentiation. The ADHeatConduction kernel implements the heat equation given by Fourier's Law where The heat flux is given as where denotes the thermal conductivity of the material. can either be an ADMaterial or traditional Material.
This class inherits from the ADDiffusion class.
Same as Diffusion in terms of physics/residual, but the Jacobian is computed using forward automatic differentiation

#
# This is a test of the piece-wise linear strain hardening model using the
# small strain formulation. This test exercises the temperature-dependent
# yield stress.
#
# Test procedure:
# 1. The element is pulled to and then beyond the yield stress for a given
# temperature.
# 2. The displacement is then constant while the temperature increases and
# the yield stress decreases. This results in a lower stress with more
# plastic strain.
# 3. The temperature decreases beyond its original value giving a higher
# yield stress. The displacement increases, causing increases stress to
# the new yield stress.
# 4. The temperature and yield stress are constant with increasing
# displacement giving a constant stress and more plastic strain.
#
# Plotting total_strain_yy on the x axis and stress_yy on the y axis shows
# the stress history in a clear way.
