Stress and contact heterogeneities are quite apparent in many material processing applications, especially in powder compaction or while handling of powders and grains. On this account, a detailed study on response due to solid contact during collision and compression are quite significant. Thus, a new computational tool has been developed with an aim to model a multi-contacting systems. This is based on a penalty method and has been implemented in the finite volume open-source software environment ‘foam-extend-4.0’.
In order to investigate such a process representing a granular material compression, a confined fixed domain with moving punches at the top and bottom, has been examined for disk particles with varying size and configuration. As a step of verification, the contact properties (e.g. force, stress, strain) result shows an excellent agreement with the analytical solution. Thus, this tool is able to track multi-contact deformation in a dense particles system.
