Deep drawing is a production process during which a flat sheet of metal, commonly referred as a blank, is deformed to a desired shape on a press, keeping its mass and material integrity. Due to such effects as thinning, tearing, wrinkling and elastic springback it is necessary to simulate the production process for each part to avoid costly prototype building and trial-and-error process optimization. Such a simulation can be done utilizing the Finite Element Analysis. Adapted to the needs of a deep drawing simulation, the engineer can get an overview of the mentioned above effects. However, additional information, such as which elements are in contact at the last steps of the simulation is needed and cannot be provided by the simulation environment. For this purpose, a program for finding elements in contact within finite element meshes has been developed, resulting in new application possibilities for a simulation engineer.     «
