A triangulated-mesh model, combined with elastic membrane model, was developed to simulate the soft-particle compression, which involves two parallel plates squeezing a soft particle. With this model, we studied a range of mechanical properties of the soft particle including the deformation (shape profile, which was visualized through our simulation) of the membrane, the strength response, stress-relaxation and viscoelastic behaviors of the particle. These results obtained by our model were compared with some existing experiments, indicating excellent agreements.

Key words: simulation, soft particle, deformation, mechanical properties
