Descriere

Creează o constrângere MEF pentru contactul între două suprafețe.

Cum se folosește

  1. Click pe sau alegeți ModelMechanical Constraints Constraint contact din meniul de us.
  2. Select the master face.
  3. Select the slave face.
  4. Enter a contact stiffness.
  5. Enter a friction coefficient.

Limite

  1. Constrângerea de contact poate fi aplicată numai la două fețe.

Note

  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
