Mechanical response of dense pedestrian crowds to the crossing of intruders
Alexandre Nicolas, Marcelo Kuperman, Santiago Ibanez +2
The increasing number of mass events involving large crowds calls for a better understanding of the dynamics of dense crowds. Inquiring into the possibility of a mechanical descrip…
Experimental Study of Collective Pedestrian Dynamics
Cécile Appert-Rolland, Julien Pettré, Anne-Hélène Olivier +4
We report on two series of experiments, conducted in the frame of two different collaborations designed to study how pedestrians adapt their trajectories and velocities in groups o…
A counterintuitive way to speed up pedestrian and granular bottleneck flows prone to clogging: Can 'more' escape faster?
Alexandre Nicolas, Santiago Ibáñez, Marcelo Kuperman +1
Dense granular flows through constrictions, as well as competitive pedestrian evacuations, are hindered by a propensity to form clogs. We usesimulations of model pedestrians and ex…
Orientation of plastic rearrangements in two-dimensional model glasses under shear
Alexandre Nicolas, Jörg Rottler
The plastic deformation of amorphous solids is mediated by localized shear transformations involving small groups of particles rearranging irreversibly in an elastic background. We…
