Stress history effects on dynamic modulus of clay
Remolded kaolinite and bentonite triaxial specimens were subjected to isotropic consolidation pressures of 10 to 100 psi and over-consolidation ratios of 1 through 10; vibrations were applied to top of each specimen, and dynamic shear modulus was determined by resonant-column technique; for normally consolidated conditions, shear modulus increased with 1/2 and 2/3 power of effective pressure for kaolinite and bentonite, respectively; for overconsolidated kaolinite, regression analysis indicated shear modulus depends on both void ratio and effective pressure; for overconsolidated bentonite, shear modulus is predominantly influenced by void ratio.
