Stress-strain hysteresis shape estimation of different soils using deformation-history integral (DHI) model

A. Vatanshenas, T. Mori, M.S. Farhadi & T. Länsivaara
Different soils show different nonlinear stress-strain patterns. Hence, it is difficultto come up with a general model to predict these shapes. This study investigated the suitability of the DHI model which was not originally formulated for geomaterials. This model was applied to different loading cycles of various types of soils and the model’s variables were optimized using nonlinear generalized reduced gradient (GRG) method. Up to five hysteresis springs were considered in the study. The computed...
