Abstract
New features of nonisothermal compaction kinetics are established: presence of an induction period during which compaction hardly occurs and the possible “explosive” nature of compaction. Numerical calculations make it possible to refine the picture of compaction in a wave regime and to separate two autonomous processes: propagation of a compression zone within the space from layer to layer and material compaction with time in the compression zone. It is shown that with an increase in the height of a compressed specimen there is a continuous transition from a regular regime to a wave regime of compaction.
