moreThis paper presents a hyperbolic mathematical model to predict the complete stress-straincurve of drained triaxial tests on uniform dense sand. The model was formed in one equation withmany parameters. The main parameters that are needed to run the model are the confining pressure,angle of friction and the relative density. The other parameters, initial and final slopes of the stressstrain curve, the reference stress and the curve-shape parameter are determined as functions of theconfining pressure, angle of friction and the relative density using best fitting curve technique from theexperimental tests results. Drained triaxial tests were run on clean white uniform sand to utilize andverify this model. These tests were carried out at four levels of confining pressure of 100, 200, 300 and400 kPa. This model was used to predict the stress-strain curves for drained triaxial tests on quartzsand at different relative density using the data of Kouner [1] . The model predictions were comparedwith the experimental results and showed good agreements of the predicted results with theexperimental results at all levels of applied confining pressures and relative densities.
