N2 - This paper presents an experimental and constitutive study of compaction banding in Tuffeau de Maastricht, a bioclastic sedimentary limestone exhibiting up to 52% of porosity. An elasto-plastic constitutive model is used to simulate the mechanical behavior of the limestone within the compaction localization regime. It is shown that the simulated macroscopic behavior is in good agreement with the experimental data. In addition, image processing tools have been used to perform full-field measurements elucidating the mechanics of initiation and propagation of localized compaction zones. These findings emphasize the complex nature of localized compaction in porous rocks and represent a preliminary step towards the integrated use of multi-scale testing and mechanical modeling for their characterization across scales.
