抄録: | Volume change behaviour under spherical or shearing stress condition and the relation be-tween stress ratio and strain increment ratio, of a remoulded-reconsolidated clay in N.C. or O.C.States, have been studied experimentally and their characteristics are clarified with mathematicalformulations in this paper.The swelling and recompression characteristics under spherical stress state can be evaluatedfrom the results already obtained. The mathematical expressions for the positive dilatant behavi-our in O.C. state are given. It is clarified that the relation between stress ratio and strain incre-ment ratio, under p-const. Convetional triaxial condition, should have the different forms dependenton the values of O.C.R., and these relations have been used to determine the plastic potentialfunction for p-const. Condition. Another plastic potential function, for η-const. Condition, is alsodetermined.Finally, a mathematical plasticity model is given, and some calculated stress-strain relation-ships are compared with test results along fundamental stress paths. |
