The execution of the simulations using the elastoplastic model for soil is useful for constructing rationally and economically the foundation of the structure. It is one of the models in which the subloading surface model can most appropriately describe the stress-strain behavior of the soil in various elastoplastic models. In this study, the influence of the soil particle shape for the mechanical behavior of the granular materials like sand was revealed from the laboratory experiments. Then, it was presented the determination method of the material parameters of the subloading surface model based on the particle shape.
