A simple nonlinear-elastic model for prediction of lime stabilized clayey sand behavior

Abstract

This study was undertaken to determine the mechanical behavior of lime- stabilized clayey sands. The variations of compressive and tensile strengths of materials were investigated. Uniaxial and indirect tensile tests were performed and the results of stress-strain diagrams were used to present a simple nonlinear- elastic model. The results show that a simple parabolic elastic model can predict the stress-strain relation before failure. A matrix of elastic coefficients is then presented based on the suggested model and the stress level.
