Example: Impulsively Loaded Cap with Shells and Solids

Filename: constrained.shell_solid.dome.k

Description:
A dome has an impulsive pressure load. The dome contains shell and brick
element joined with shell-brick interfaces.

Model:
Only 1/4 of the dome is modeled due to symmetry. The dome shells are
Hughes-Liu shell elements with three integration point through the thickness.
Four shell elements have a pressure load of 5,308 psi over 0.0017246
square inches. The termination time is 0.0004 seconds.

Input:
The model contains one shell-brick group that has 7 shell nodes tied to 5 brick
node (*CONSTRAINED_SHELL_TO_SOLID). The model contains four pressure surfaces
(*LOAD_SEGMENT). Five nodes are written to the time history ASCII database file
nodout (*DATABASE_HISTORY_NODE, *DATABASE_NODOUT).

Results:
The plots show the response of the dome.
