Title

Elasticity and Normality in Soil - Experimental Examinations

Abstract

Fundamental premises of modern soil mechanics theories are that soil deformations are elastic before yield and elasto-plastic after yield, and that the flow rule for plastic strains is associated. Previous attempts at experimental examinations of these premises have met several difficulties associated with elastic nonlinearity, measurement of plastic strains and identification of the current yield surface. For materials which are both elastic and for which the flow rule is associated the stress-strain matrix has particular features which are observable in special stress path laboratory tests. These special tests have been carried out on reconstituted samples of London Clay, Cowden Till and Speswhite kaolin.
