Pile of sand simulation. Factor a is the ratio between initial height and initial radius of the pile.
Pile of sand under gravity, Drucker-Prager yield criterion, a = 0.55
Pile of sand under gravity, Mohr-Coulomb yield criterion, a = 0.55
Pile of sand under gravity, Drucker-Prager yield criterion, a = 2.75

Collision between two Ceres-sized (mass) objects, blue are ice/water particles, yellow are basalt particles
The radii are 437 km and 509 km, the collision speed is 630 m/s. The model includes: von Mises yield strength, tensile
damage model (following Benz & Asphaug 1995), self-gravity and Tillotson equation of state. Total simulation time is
24 hours. The final outcome is merging.
