Sintering and Compaction of Powder Packings

I worked on constitutive models for ceramic and metal powder packings and studied problems of thin film sintering, composites, viscoelastic sintering, etc. The pictures below show results from some of these problems.

Picture (E. Liniger & R. Raj) of a 2D sintering packing that was modelled using a network of beams.
