Square Plate Transient Forced Vibration (thick shell mesh)
Transient analysis is perfomed to obtain the response of a plate subjected to a suddenly applied pressure on its top. Differences between S/R IPI thick shell (elform 2), assumed strain IPI thick shell (elform 3) and assumed strain RI thick shell (elform 5) can be studied. Example 15 from Introductory Manual for LS-DYNA Users by James M. Kennedy.
