3. Modeling A

3.1. Characteristics of modeling

Modeling: DKT

3.2. Characteristics of the mesh

Knots: 16

Meshes: 9 QUAD4

3.3. Tested sizes and results

Three calculations are performed with the DYNA_NON_LINE operator, the first with an explicit schema, the second with a weakly damped implicit schema (HHT) and the third with a heavily damped implicit schema (HHT).

All tested values are taken at time \({t}_{\mathrm{max}}=0.0012s\).
