# Square Plate Transient Forced Vibration (solid mesh) — Welcome to LS-DYNA Examples

Home » Knowledge Base » Simple Examples » Intro by Jim Kennedy » Square Plate Transient Forced Vibration (solid mesh)

Transient analysis is perfomed to obtain the response of a plate subjected to a suddenly applied pressure on its top. Differences between constant stress solid (elform 1), fully integrated S/R solid (elforms 2, -1 and -2) and fully integrated quadratic 8 node element with nodal rotations (elform 3) can be studied. Example 14 from Introductory Manual for LS-DYNA Users by James M. Kennedy.
