Prediction of Stress–Strain Response for Malaysian Granitic Residual Soil (Grade VI) in a Range of Effective Stresses, According to Rotational Multiple Yield Surface Framework

Abstract

The conventional soils volume change models which are based on the effective stress concept are not accurate to model true volume change behavior of unsaturated soil solely. It seems that the effect of shear strength in interaction of effective stress is essential to be incorporated in these frameworks. Rotational multiple yield surface framework (RMYSF), which introduced by Md.Noor and Anderson (16th South East Asian Geotechnical Conference Kuala Lumpur, 2007) [21] is developed based on the concept. In this paper, the framework has been examined for Malaysian granitic residual soil grade VI. With the aim of this process, the stress–strain curves were predicted using the framework. Beside that, the stress–strain curves have been obtained from consolidated drained triaxial tests under various effective stresses and then the results were compared with the predicted ones. The result shows a good agreement between the laboratory stress–strain curves and predicted ones from the framework.
