Block Pressing on Arch

Application ID: 73891


This conceptual example shows how to calculate critical points in models with contact. The model consists of a block modeled with the Solid Mechanics interface pressing on an arch modeled with the Shell interface. The contact problem is solved using the augmented Lagrangian method. The block is loaded with a displacement controlled boundary load and is incrementally pressed toward the arch. During loading, there is a snap-through behavior of arch but the solution remains stable.

The model is based on a benchmark problem from the textbook “Computational Contact Mechanics” by P. Wriggers.

This model example illustrates applications of this type that would nominally be built using the following products:
