9.1. Characteristics of modeling#

A 3D modeling with elements HEXA8 testing the functionalities of node-mesh contact with friction treated with the continuous method for contact friction has been implemented.

The game between the skate and the frame is defined by a function using the keyword « DIST_2 ».

To avoid rigid body movements, the skate is held in place by springs of low stiffness:

RES_LAT

: \(k\mathrm{=}1N\mathrm{/}\mathit{mm}\)

RES_FOND

: \(k\mathrm{=}1N\mathrm{/}\mathit{mm}\)

RES_HAUT

: \(k\mathrm{=}20N\mathrm{/}\mathit{mm}\)

Boundary conditions:

Free end of the springs: \(\mathrm{DX}=\mathrm{DY}=\mathrm{DZ}=0\).

Built: \(\mathrm{DX}=\mathrm{DY}=\mathrm{DZ}=0\).

9.2. Characteristics of the mesh#

Number of knots: 269

Number and type of meshes: 129 HEXA8, 103 QUAD4
