ADComputeLinearElasticStress
Compute stress using elasticity for small strains
Description
This material, ADComputeLinearElasticStress computes the elastic stress for a total and small strain formulation: this stress class is compatible with the ADComputeSmallStrain type of strain calculators, including those for non-Cartesian coordinate systems. This stress calculator class can be used with any coordinate system to calculate the elastic stress response for a small total formulation strain.
Elastic materials do not experience permanent deformation, and all elastic strain and elastic stress is recoverable. Elastic stress is related to elastic strain through the elasticity tensor
where is the total strain formulation; this strain measure is also the sum of the mechanical elastic strain and any eigenstrains in the system.

# This tests the thermal expansion coefficient function using both
# options to specify that function: mean and instantaneous. There
# two blocks, each containing a single element, and these use the
# two variants of the function.
# In this test, the instantaneous CTE function has a constant value,
# while the mean CTE function is an analytic function designed to
# give the same response. If \bar{alpha}(T) is the mean CTE function,
# and \alpha(T) is the instantaneous CTE function,
# \bar{\alpha}(T) = 1/(T-Tref) \intA^{T}_{Tsf} \alpha(T) dT
# where Tref is the reference temperature used to define the mean CTE
# function, and Tsf is the stress-free temperature.
# This version of the test uses small deformation theory. The results
# from the two models are identical.

# Wave propogation in 1D using HHT time integration in the presence of Rayleigh damping
#
# The test is for an 1D bar element of length 4m fixed on one end
# with a sinusoidal pulse dirichlet boundary condition applied to the other end.
# alpha, beta and gamma are HHT time integration parameters
# eta and zeta are mass dependent and stiffness dependent Rayleigh damping
# coefficients, respectively.
# The equation of motion in terms of matrices is:
#
# M*accel + (eta*M+zeta*K)*((1+alpha)*vel-alpha*vel_old)
# +(1+alpha)*K*disp-alpha*K*disp_old = 0
#
# Here M is the mass matrix, K is the stiffness matrix
#
# The displacement at the first, second, third and fourth node at t = 0.1 are

# This tests the thermal expansion coefficient function using both
# options to specify that function: mean and instantaneous. There
# two blocks, each containing a single element, and these use the
# two variants of the function.
# In this test, the instantaneous CTE function is a linear function
# while the mean CTE function is an analytic function designed to
# give the same response. If \bar{alpha}(T) is the mean CTE function,
# and \alpha(T) is the instantaneous CTE function,
# \bar{\alpha}(T) = 1/(T-Tref) \intA^{T}_{Tsf} \alpha(T) dT
# where Tref is the reference temperature used to define the mean CTE
# function, and Tsf is the stress-free temperature.
# This version of the test uses small deformation theory. The results
# from the two models are identical.
