A semi-analytic model of the bouncing barrier for protoplanetary dust aggregates
A semi-analytic model using elastoplastic contact mechanics and weakest-link fracture statistics reproduces the sticking-bouncing boundary from DEM simulations and places the bouncing barrier within ALMA-inferred size-velocity ranges for moderately porous aggregates.
