Volumetric Strain Mechanisms and Induced Anisotropy Analyses in Clayey Materials

摘要

The study deals with an experimental analysis of the coupling between the macroscopic scale behavior and the local deformation properties of clayey materials, with a special focus on the induced anisotropy phenomenon. The analysis was first conducted on a remolded saturated synthetic clay called kaolin P300, then on deepwater marine clayey sediments from the Gulf of Guinea where the influence of the structure (cementation and fabric) was examined.
