Descriere
Creează o constrângere MEF pentru contactul între două suprafețe.
Cum se folosește
Limite
- Constrângerea de contact poate fi aplicată numai la două fețe.
Note
CalculiX
- Rigiditatea contactului trebuie să fie de 10 ori mai moale (modulul Young) decât modulul de a avea un contact dur. Cu cât este mai mare valoarea rigidității de contact, cu atât este mai mare contactul dintre suprafețe.
- Fața slave este fața care intră în fața principală și, prin urmare, are mai multe deformări.
- Tabelul *CONTACT PAIR este utilizat pentru modelarea contactului în CalculiX. Constrângerea folosește contactul optimizat cu constrângeri față-în-față și formula de contact este explicată în detaliu aici la http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node112.html
