Abstract The formation of a neck between spherical particles by surface and grain boundary diffusion is modelled by three independent methods. First, an accurate numerical solution is provided. Second, closed-form similarity solutions are derived, which are exact for short times in the limiting cases of small and large δDs/δDb ratios. Third, approximate analytical solutions are developed based on a thermodynamic variational principle. The latter method is probably the most versatile on e, since… CONTINUE READING
