Analysis of Cyclic Behavior of Geomaterials Using Dissipated Energy Concept
Strain energy method is a novel approach that can be utilized to better understand the cyclic behavior of geomaterials subjected to repeated loading in triaxial tests. In order to characterize the dissipation of the energy in the particulate systems, it is necessary to mechanistically identify the factors that influence the energy stored and restored in each loading application. The main motivation for this study was to successfully understand the manner in which the generated hysteresis loops are affected by moisture state, fines content, and constant confining pressure stress paths. A comprehensive laboratory experiment consisted of two different gradations of a limestone source molded at two different moisture states were considered in this study. The specimen were subjected to two series of constant confining pressure stress path tests, which were aimed to capture the hardening and softening behavior of geomaterials. Analysis of the cyclic test demonstrated that moisture and fines content both act in a synergistic manner.
