The region modeled is shown shaded in the problem sketch. The ESURF command is used to automatically generate the contact and target elements between “contactor” nodes on the upper cylinder and “target” nodes on the lower cylinder. The default value of contact stiffness FKN is chosen while performing a solution using Augmented Lagrangian contact algorithm (KEYOPT(2) = 0) whereas no contact stiffness input is required to be specified while performing a solu...
