Experimental Study of Small Strain Stiffness of Unsaturated Silty Clay

The small strain stiffness of saturated soils has been extensively studied in the past decades, and therefore the literature database of small strain stiffness of different soils is vast and contains the necessary information for development and calibration of numerical models. However, there is a lack of data of small strain stiffness in case of unsaturated soils. This paper presents the stiffness of unsaturated silty clay in both small and very small strain regions.
