STRESS-STRAIN RELATIONSHIPS OF SANDS BASED ON THE MOBILIZED PLANE

Taking special notice of the similarity of shear characteristics between sands and clays, the author sought to apply to clays the stress-strain relationships which were derived from the microscopic analysis and which were experimentally verified with reference to sands and other granular materials. The stress-strain relationships were verified with respect to measured data of drained triaxial compression tests on various kinds of normally consolidated and overconsolidated clays and the related microscopic mechanism was also considered. It was shown from the test results that the shear phenomena of sands and clays could be analyzed on the basis of the same principle, suggesting that they might occur in a fundamentally similar mechanism.
