A new contact detection algorithm for non-spherical particles in the Discrete Element Method

Abstract:

Houlsby (2009) presented the concept of "potential particles", a method for modelling non-circular particles for the Discrete Element Method (DEM). Potential particles can assume a wide variety of shapes, ranging from circular to almost polygonal in 2-D and from spherical to almost polyhedral in 3-D. Here we present a new algorithm for the contact detection between potential particles in both 2-D and 3-D. The contact detection problem is formulated into a Second-Order Cone Program (SOCP) and ...
