The mechanical characteristics of soft particle systems, such as hydrogels, are expected to be very complex due to the additional degree of freedom of deformation within each particle and its details have not been well understood. In this study, we attempt to develop a numerical model based on the boundary element method (BEM) toward the elucidation of mechanical behaviors of soft particle systems in detail. As a first step, the deformation behavior of a single soft particle is studied using the proposed model. The results of a compression test show that, within the small deformation, the strain-force relation is generally consistent with experiments using hydrogel particles while the force becomes much smaller than the experiments when the deformation becomes large.
