Abstract (en)

Normal impact of the stiff silica particle with soft contact at rigid or deformable substrate was investigated numerically. The ultrafine particle presents a sphere with radius R = 0.6 μm. The nonlinear-dissipative contact model with adhesion was developed to model normal contact forces. Deformation behaviour is described by elastic-plastic contact model with loading and unloading. Damping was described by the nonlinear Tsuji model. The load-dependent detachment is of the non-linear character. The above approach was implemented into the Discrete Element Method code DEMMAT. Different dissipation mechanisms were examined. Numerical results are compared with experiment of Poppe et al., 2000. It was shown that experimentally observed scattering of the coefficient of restitution may be enveloped by various dissipation mechanisms.
