Following a model for the sintering of a row of grains by Sun et al. (1996), a simplified model is developed for cavity growth along a grainboundary by surface and grain-boundary diffusion. The cavity surface is approximated by two arcs of equal radius truncated by the grain-boundary. The arcs evolv
