Section
Examples for 'section' card in the input deck of LS-DYNA.
Shell 1
A fuse plate is used to connect a cut in a wide flange beam. The beam is loaded at an end, putting the fuse plate in tension. In this loading condition, the fuse plate exhibits a great deal of hourglassing.
Shell 2
A cantilever beam has a concentrated load, and then the beam vibration critically damps. Lobatto integration rules place the quadrature points on the true surfaces of the shell. [ See Hughes].
Solid
A rigid beam strikes a post near the top of the post. There is hole cut out of the lower portion of the post to reduce its' section modulus and thus, allow it to snap-off easier. In the first model, the post begins to break, but hourglassing starts to dominate the solution and the post does not completely snap.
