Computational modelling of compaction bands in geomaterials

Abstract

This research represents a theoretical and computational study of compaction bands in geomaterials. The first part of the work establishes a robust numerical framework for a wave-mechanics approach to the compaction band process, showing its versatility in finding solutions for a wide range of scenarios. The second part deals with compaction bands as a bifurcation problem in rate-dependent critical-state based materials for well-known geomechanical stress paths, establishing a series of statements for their onset conditions.
