    Abstract

    There is a need for an improved understanding of rate effects over a wide range of strain rates in order to improve the modelling and analysis of installation effects. Using triaxial testing on reconstituted kaolin over a wide strain rate range this paper examines the impact of strain rate on the aspects of soil response which are important in the analysis of installation effects. It is demonstrated that shear strength, small strain stiffness and the elastic shear strain threshold are rate dependent. The implications of this for a common stiffness degradation model are analysed and an improved model proposed.
