3. Modeling A

3.1. Characteristics of modeling

PLAN (QUAD4, TRIA3)

3.2. Characteristics of the mesh

Number of nodes:	100
Number of meshes and types:	117 (45 QUAD4, 72 TRIA3)

3.3. notes

The discretization in time steps is as follows:

10 steps for	\([0.,\mathrm{5.00D0}]\)	or \(\Delta t=0.5\)
9 steps for	\([\mathrm{5.00D0},\mathrm{5.00D1}]\)	or \(\Delta t=5.\)
9 steps for	\([\mathrm{5.00D1},\mathrm{5.00D2}]\)	or \(\Delta t=50.\)
38 steps for	\([\mathrm{5.00D2},\mathrm{4.30D3}]\)	or \(\Delta t=100.\)
1 step for	\([\mathrm{4.30D3},\mathrm{4.32D3}]\)	or \(\Delta t=20.\)
