T. Wichtmann, Auteur ; T. Triantafyllidis, Auteur |The modulus degradation curves, G(γ)/Gmax, and the damping ratio, D(γ), of 27 clean quartz sands with specially mixed grain size distribution curves were measured in approximately 280 resonant column tests. For each material, tests with various [...]

Influence of the grain-size distribution curve of quartz sand on the small strain shear modulus Gmax
T. Wichtmann, Auteur ; T. Triantafyllidis, Auteur |The paper presents a study of the influence of grain-size distribution curve on the small strain shear modulus Gmax of quartz sand with subangular grain shape. The results of 163 resonant column tests on 25 different grain-size distribution curv[...]

T. Wichtmann, Auteur ; H. A. Rondon, Auteur ; A. Niemunis, Auteur |The present paper discusses the application of a high-cycle accumulation (HCA) model originally developed for sand for the prediction of permanent deformations in an unbound granular material (UGM) used for base and subbase layers in pavements.
