Randomized trial investigates cyclic loading effects on granular materials, suggesting mechanisms for behavior prediction.
Key Points
This research aims to analyze how granular materials behave under cyclic shear loading, focusing on grain-scale interactions and bulk response.
Laboratory experiments on dry, cohesionless granular materials under quasi-static cyclic simple shear loading.
Utilization of the Granular Element Method (GEM) for estimating interparticle contact forces from grain-scale data.
Development of an upgraded shear apparatus for controlled cyclic loading with multiscale imaging and tracking methods.
Cyclic simple shear produces direction-dependent and history-dependent responses associated with packing conditions and confinement.
Densely packed assemblies show stronger initial load-bearing structures that weaken with cycling, whereas loosely packed systems exhibit progressive compaction.
Asymmetric stress and deformation responses were observed, indicating complex internal load transfer mechanisms over repeated cycles.
