WebThe continuum analysis of each particle, which is represented by a spheropolygon element, is performed using the BEM method. This computational framework allows an instant calculation of the stress field and therefore provides important insights into the roles of sub-particle stress in particle breakage. It is an effective tool for reproducing ...
