Contact Analysis of a Snap Hook Using a Penalty Formulation

Application ID: 12577


This example simulates the insertion of a snap hook in its groove.

Here, the purpose of the contact modeling is only to transmit correct contact forces in a global sense into the model, which is a situation well suited for using the penalty method.

This contact algorithm is based on the penalty factor formulation related to the penetration of the solid parts in contact. In some cases, this approach can result in faster computations and provide smoother convergence when compared to the Augmented Lagrangian method.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
