Abstract
The quasistatic mechanical response of soils under cyclic loading using a discrete model of randomly generated convex polygons is investigated. A sequence of regimes is exhibited by this response, each one characterized by a linear accumulation of plastic deformation with the number of cycles. A quasiperiodic ratchetlike behavior is observed at the contacts at the grain level, which excludes the existence of an elastic regime. Exploration of the role of friction in the permanent deformation of unbound granular materials subjected to cyclic loading is allowed by the slow dynamics.
