Memory of the unjamming transition during cyclic tiltings of a granular pile
Memory of the unjamming transition during cyclic tiltings of a granular pile
Discrete numerical simulations are performed to study the evolution of the microstructure and the response of a granular packing during successive loading-unloading cycles, consisting of quasistatic rotations in the gravity field between opposite inclination angles. We show that internal variables---e.g., stress and fabric of the pile---exhibit hysteresis during these cycles …
