Characterization of the material response in the granular ratcheting [PDF]

, 2005
The existence of a very special ratcheting regime has recently been reported in a granular packing subjected to cyclic loading \cite{alonso04}. In this state, the system accumulates a small permanent deformation after each cycle.

A model to predict changes in resilient modulus resulting from wetting and drying

Infraestructura Vial, 2016
The resilient modulus of a soil is an important parameter needed for pavement design. However, this parameter experiences post-compaction seasonal changes during the service life of the pavement as a result of wetting or drying of the soil during dry or ...
