A soft particle dynamics method based on shape degrees of freedom
Yohann Trivino, Vincent Richefeu, Farhang Radjai +2
In this paper, we present a 2D numerical model developed to simulate the dynamics of soft, deformable particles. To accommodate significant particle deformations, the particle surf…
