A Bonded-Particle Discrete-Element Model with Self-Gravity for the Collision and Reaccumulation of Rubble-Pile Asteroids: Formulation and Numerical Protocol
Yohann Trivino
I present a discrete-element approach developed to study the collisional and gravitational evolution of small self-gravitating granular aggregates. Each body is represented as a co…

Gravitational aggregation regimes: critical dissipation threshold, optimal rigidity and fractal transition
Yohann Trivino
I present a three-dimensional Discrete Element Method study of self-gravitation and contact mechanics in cold granular assemblies. The model couples direct Newtonian attraction bet…

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…
