42.1. Introduction

In this example, a multi-strand wire is joined to an electrical terminal (connector) through a mechanical deformation process known as crimping. The U-shaped portion of the connector (the grip) is folded around the wires by a rigid punch, forming a B-shaped crimp which provides connectivity between the wires and the electric terminal.

Due to the complexity of this model, defining all possible contact surfaces by the pair-based contact method would be a difficult and time-consuming task. By using the general contact method, contact surfaces are created automatically; only a limited number of contact surfaces require the specification of non-default contact properties. Both flexible-flexible and rigid-flexible contact are modeled.
