The Universal Void Ratio Function for Small Strain Shear ...

Based on this, a theoretical void ratio function for small strain shear modulus, F(e) = (1+e) -3, is obtained. The theoretical function is fit well to the experimental data for both clays and sands over a wide void ratio range, and therefore can be considered as the universal void ratio function.
