The Minkowski overlap and the energy‐conserving contact model for discrete element modeling of convex nonspherical particles

A unified contact overlap, termed the Minkowski overlap, between any two shapes is proposed in this article. This overlap is based on the concept of the Minkowski difference of two shapes, and particularly on the equivalence between the contact state of the two shapes and the location of the origin...
