Workbench Mechanical - Introduction to Contact ... Contact Stiffness and Penetration Training Manual • For bonded contact, Workbench-Mechanical uses Pure Penalty formulation with large Normal Stiffness by default. – This provides good results since the contact stiffness is high, resulting in small/negligible penetration. – MPC formulation is a good alternative for bonded contact because of its many nice features. • For frictionless or frictional contact, consider using either Augmented Lagrange or Normal Lagrange methods. – The Augmented Lagrange method is recommended, as noted previously, because of its attractive features and flexibility. – The Normal Lagrange method can be used if the user does not want to bother with Normal Stiffness value and wants zero penetration. However, note that the Direct Solver must be used, which may limit the size of the models solved. ANSYS, Inc. Proprietary © 2009 ANSYS, Inc. All rights reserved. 3-18 April 30, 2009 Inventory #002659
