<strong>LS</strong>-<strong>DYNA</strong> Manual Section: *CONTROL_SHELL<br />

Example of: Twisted Cantilever Beam<br />

Example Filenames: beam_twist.key<br />

Description:<br />

A beam twisted 90 degrees about its length is constrained on one edge and has a point load<br />

prescribed normal to the opposite end of the beam.<br />

Model:<br />

The beam measures 12.00 × 1.10 × 0.32 cubic inches. A concentrated load of 0.1667 pounds is<br />

applied to each node on the end in both the x and y direction. The calculation terminates at 0.0018<br />

seconds.<br />

Input:<br />

This model uses the Hughes-Liu formulation. The element has the shell normal update calculation<br />

performed at each nodal fiber every cycle. (*CONTROL_SHELL)<br />

Results:<br />

The beam oscillations about a neutral amplitude.<br />

Reference:<br />
