Abstract
Ceramics can deform non-elastically under compression and shear by sliding and ride up of fragments or grains, with accompnying competition between dilatancy and pore compaction. This paper describes a micromechanical model of such deformation based on multiplane plasticity and an analogy to the dynamics of atomic dislocations.
