      abstract     = {The microscopic principle of the stress-assisted sintering
                      is that the relative velocity between two adjoining
                      particles is proportional to the sum of the sintering force
                      and the mechanical force transmitted by the contact. Here,
                      we simulated sintering of four particles by coupled grain
                      boundary diffusion and surface diffusion, in order to
                      analyze how the sintering force varies with the evolution of
                      particle shape, i.e., pinch-off of pore channel, formation
                      and shrinkage of a closed pore. The shrinkage rate of the
                      pore volume was proportional to the relative velocity of
                      particles, then, to the sintering force. We discussed the
                      effect of mechanical stress on sintering also.},
