Sliding Wedge

Application ID: 364

A contactor wedge is subject to a gravity load and is forced to slide due to a boundary load over a rigid target wedge surface, both infinitely wide. Horizontal linear springs are also connected between the left vertical boundary and the ground.

This is a large sliding problem including contact pressure for a constant contact area and friction force calculations. A penalty/barrier method is used to solve the contact problem and a Coulomb friction model is used to calculate the friction forces. This is a NAFEM benchmark model described in the NAFEM publication NAFEMS Benchmark Tests for Finite Element Modeling of Contact, Gapping and Sliding.

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.
