Chemically Induced Strain Localization in Geomaterials
Abstract Deformation bands play an important role in reservoir engineering, geological storage, underwater landslides and slow geological procedures related to creep and aseismic slip. Various mechanisms can be involved at different scales and may be responsible for deformation bands. Mechanical and chemical degradation of the grain skeleton is a softening mechanism that leads to compaction, shear or even dilation band formation. The present study is twofold. On one hand it focuses on the mathematical modeling of chemically induced strain localization instabilities in porous rocks and on the other hand it explores the conditions for their creation. The post localization regime is then studied by numerically integrating the governing equations of the system.
