      abstract     = {The microstructural evolution during sintering involves the
                      formation and pinch-off of pore channels. The sintering of 3
                      particles in 3 dimensions is a simple model for studying the
                      pinch-off of a pore channel. We simulate the solid-state
                      sintering of 3 particles by using Brakke's Surface Evolver
                      program, which incorporates coupled grain-boundary diffusion
                      and surface diffusion. The pinch-off of pore channel divides
                      the sintering process into 2 stages; the initial stage and
                      the later stage. The contact area has a noncircular shape
                      bounded by both surface triple junction and triple junction
                      in the later stage. A general method is presented to
                      determine the sintering force acting on the noncircular
                      contact. The mechanical approach of densification, where the
                      relative motion of particles is driven by both sintering
                      force and applied force, is applicable not only for the
                      initial stage, but also for the later stage.},
