3.1. Characteristics of modeling#

Discreet element in type translation DIS_T

Characteristics of the elements:

At nodes \(\mathit{P1}\) and \(\mathit{P2}\): mass matrices of type M_T_D_N with \(m\mathrm{=}100\mathit{kg}\).

Between \(\mathit{P1}\) and \(\mathit{P2}\): a K_T_D_L stiffness matrix with \({K}_{x}\mathrm{=}{10}^{6}N\mathrm{/}m\)

Boundary conditions:

All degrees of freedom are locked except degree of freedom \(\mathit{DX}\) from node \(\mathit{P2}\).

Number of knots: 2

Number of meshes and types: 1 SEG2, 2 POI1
