Effect of Fast Constant Loading Rates on the Global Behavior of Sand in Triaxial Compression. Suescun-Florez, E. & Iskander, M. GEOTECHNICAL TESTING JOURNAL, 40(1):52-71, AMER SOC TESTING MATERIALS, 1, 2017. abstract bibtex Loading rate effects on the global stress-strain behavior of sand were
investigated by performing triaxial compression tests on air-dried sand
specimens. Siliceous and calcareous sands were subjected to triaxial
compression at various constant strain rates to investigate the rate
effects, initial density, confining pressure, shape and size of grains,
as well as type of sand on the mechanical behavior of granular
materials. The results indicate that silica sand and coral sand exhibit
different rate dependency in terms of stiffness and peak normal stress.
In general, strain rate effects are highly dependent on confining stress
and relative density, with dense samples subjected to the highest
employed confining stress exhibiting the most pronounced effects to
variation in strain rates. Calcareous sand also exhibited a higher
strain rate dependency than silica sand.
