NodalStickConstraint
buildconstruction:Undocumented Class
The NodalStickConstraint has not been documented. The content listed below should be used as a starting point for documenting the class, which includes the typical automatic documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.

# Test for glued beam constraint.
#
# Using a simple L-shaped geometry with a glued constraint at the
# corner between the two beams. The longer beam properties and loading is
# taken from an earlier beam regression test for static loading. The maximum
# applied load of 50000 lb should result in a displacement of 3.537e-3. Since
# the constraint is glued, the y-dir displacement of the long beam is
# 3.537e-3 and the short beam y-dir displacement is the same. The stiffness of
# the short beam is much less than the longer beam and thus should not
# significantly influence the displacement solution.

# Test for LineElementAction on multiple blocks by placing parameters
# common to all blocks outside of the individual action blocks
# 2 beams of length 1m are fixed at one end and a force of 1e-4 N
# is applied at the other end of the beams. Beam 1 is in block 1
# and beam 2 is in block 2. All the material properties for the two
# beams are identical. The moment of inertia of beam 2 is twice that
# of beam 1.
# Since the end displacement of a cantilever beam is inversely proportional
# to the moment of inertia, the y displacement at the end of beam 1 should be twice
# that of beam 2.
