LS-DYNA Manual Section: *CONSTRAINED_SHELL_TO_SOLID
Example of: Impulsively Loaded Cap with Shells and Solids
Example Filename: dome_shell-brick.key
Description:
A dome is subjected to an impulsive pressure load. The dome contains shell and brick element
joined with shell-brick interfaces.
Model:
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 seven shell-brick interfaces each containing 1 shell node tied to 5 brick nodes
(*CONSTRAINED_SHELL_TO_SOLID). The model contains four pressure surfaces
(*LOAD_SEGMENT). Four nodes are written to the time history binary database every 3 µsec
(*DATABASE_HISTORY_NODE, *DATABASE_D3THDT).
Results:
The plots show the response of the dome.
