Abstract

A model has been developed that accounts for the effect of lateral stresses on the deformation of particles occurring during die compaction. This has been examined using the model material sodium chloride. The lateral stresses were found to inhibit cracking of the particles during compaction. Agreement between the theory and experimental results was obtained.
