Description

Crée une contrainte FEM de contact entre deux surfaces.

Utilisation

  1. Cliquez sur le bouton ou dans la barre de menu FEM Contrainte de contact entre deux surfaces.

Limitations

  1. The contact constraint can only be applied to two faces.

Notes

  1. The contact stiffness should be 10 times the young's modulus of the material for hard contact. The higher the value for contact stiffness, the harder the contact between surfaces.
  2. The slave face is the face which penetrates into the master face, and therefore experiences more deformation.
  3. The *CONTACT PAIR card is used for modeling contact in CalculiX. The constraint uses Face-to-Face penalty contact and the contact formulation is explained in detail at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node112.html
