BEHAVIOR OF FROZEN CLAY UNDER CYCLIC AXIAL LOADING

Dynamic Young's modulus and damping ratio was determined for axial strain amplitudes, temperatures, frequencies, and confining pressures. For samples of the frozen Ontonagon clay of value of dynamic Young's modulus over the range of test conditions was from 50 x 10 to the third power psi to 870 x 10 to the third power psi (3.45 x 10 to the third power to Kn/sq m to 6,000 x 10 to the third power kN/sq m); the value of damping ratio was from 0.02 to 0.3. The test results indicate that the dynamic Young's modulus of frozen clay decreases with increasing strain amplitude and specific surface area; it increases with descending temperature and increasing water content and frequency. The damping ratio increases with increasing strain amplitude and ascending temperature and decreases in general, with increasing frequency. There appears to be no well-defined relationship between the damping ratio and the specific surface area or water content. Dynamic Young's modulus and damping ratio are apparently not affected by confined pressure. /ASCE/
