Node to Curved Surface Contact (TYPE16)

Interface TYPE16 will enable to define contact conditions between a group of nodes (secondary) and a curve surface of quadratic elements (main part) as shown in Figure 1 for a symmetric contact. The main part may be made of 16-node thick shells or 20 node-bricks. The Lagrange Multiplier Method (LMM) is used to apply the contact conditions. By the way that the LMM is used, no gap is necessary to be applied. Some applications of this interface are sliding contacts without gaps as in gear box modeling.
