A solution scheme for the penalty constrained contact problems is presented. The algorithm employes popular quasi-Newton solver for FE applications-the BFGS (Broyden-Fletcher-Goldfarb-Shanno) method with contact constraints enforced by the penalty method. The effectiveness of proposed solution strategy is tested by means of benchmark examples including bending dominated problems. Finally, the capability of contact solver is demonstrated in creep analysis of high pressure steam turbine casing.
