Dynamic Triaxial Test on Sand
Triaxial experiments are a common method for measuring shear strength. Usually the loading in the shear phase in these experiments are done at a quasi-static rate but in many real instances the loading is dynamic in nature. Therefore, a triaxial setup has been developed based on a Kolsky bar experimental technique to characterize the shear response of the material at high rates. Using this setup, a systematic investigation of the undrained behavior of sand at high pressures has been performed to study the rate effects on the stress-strain behavior. The dynamic experiment results show that the stress-strain response of the sand specimens is only sensitive to pressure levels while it is insensitive to loading rates.
