# 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 finite deformation theory.
# The two models produce very similar results. There are slight
# differences due to the large deformation treatment.

# Test for HHT time integration
# The test is for an 1-D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# alpha, beta and gamma are HHT time integration parameters The
# equation of motion in terms of matrices is:
#
# M*accel + alpha*(K*disp - K*disp_old) + K*disp = P(t+alpha dt)*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + alpha*(Div stress - Div stress_old) +Div Stress= P(t+alpha dt)
#
# The first term on the left is evaluated using the Inertial force
# kernel The next two terms on the left involving alpha is evaluated
# using the StressDivergence Kernel The residual due to Pressure is
# evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure
# becomes constant. Alpha equal to zero will result in Newmark
# integration.

# This tests the thermal expansion coefficient function using both

# 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.
# The two models produce very similar results. There are slight
# differences due to the large deformation treatment.

# 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.
# The two models produce very similar results. There are slight
# differences due to the large deformation treatment.
