WebShell element formulation plays a considerable role in crash worthiness simulations. RADIOSS shell elements are mainly based on Mindlin-Reissner shell theory. The formulation is then valid for moderately thick shells and for thin shells. The under-integrated elements are the most popular because of their low cost. Mesh Element Name WebThe shell element formulations are: Q4 mesh with the Belytshcko & Tsay formulation (Ishell=1, hourglass control type 1, 2, and 3) Q4 mesh with the QEPH formulation (Ishell=24) Q4 mesh with the QBAT formulation (Ishell=12) T3 mesh with the DKT18 formulation (Ishell=12) RADIOSS Options Used At one extremity of the beam, all DOF are blocked.
