7.1. Characteristics of modeling#

A D_ PLANavec modeling of the elements QUAD4testant the functionalities of node-mesh contact with friction treated with the penalized method for contact and friction has been implemented.

The play between the skate and the frame is defined by the geometric coordinates of the mesh.

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

RES_LAT

: \(k=2N/\mathrm{mm}\)

RES_HAUT

: \(k=\mathrm{0,005}N/\mathrm{mm}\)

Boundary conditions:

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

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

7.2. Characteristics of the mesh#

Number of knots: 53

Number and types of meshes: 33 QUAD4, 32 SEG2
