The crushing deformation of prismatic shell structures results from a local loss of stability and creation of the so-called local plastic fold or plastic wave. Once created, the plastic fold accommodates most of the plastic deformation in a shell. The local deformation process continues up to the point where local contacts prevent further deformation of an actual fold and induce development of subsequent fold. Such a deformation process is referred to as a progressive crushing or progressive folding process.
