Mechanical responses of soft particle packings to quasi-static deformationsare determined by the microscopic restructuring of force-chain networks, wherecomplex non-affine displacements of constituent particles cause theirreversible macroscopic behavior. Recently, we have proposed a master equationfor the probability distribution functions of contact forces and interparticlegaps [K. Saitoh et al., Soft Matter 11, 1253 (2015)], where mutual exchanges ofcontacts and interparticle gaps, i.e. opening and closing contacts, are alsoinvolved in the stochastic description with the aid of Delaunay triangulations.We describe full details of the master equation and numerically investigateirreversible mechanical responses of soft particle packings to cyclic loading.The irreversibility observed in molecular dynamics simulations is wellreproduced by the master equation if the system undergoes quasi-staticdeformations. We also confirm that the degree of irreversible responses is adecreasing function of the area fraction and the number of cycles.
