Dear all,

we open one year position (with possible prolongation) at Laboratoire de Mécanique des Solides, Ecole Polytechnique Palaiseau.

The job is concerned with kinematic analysis by digital image correlation of X-ray micro-tomography data obtained during in-situ triaxial testing of porous carbonate rocks. The aims are to charcterize localization, pore colapse and formation of compaction bands, for the purpose of underground storage and more particularly CO2 sequestration

The position starts as soon as possible 2023, is financed by the Interdisciplinary Center E4C (Energy for Clamate) and relates to CO2 geological sequestration.

Please, find details bellow:

Measurements of 3D full mechanical fields in porous carbonate rocks by digital image correlation and application to for geological sequestration of CO₂

The general topic is concerned with energy transition and more particularly with underground sequestration of carbon dioxide in porous carbonate reservoir rocks.

Carbonate reservoir rocks present pronounced multiscale microstructural heterogeneities, which complicates the modeling of their short term hydro-mechanical behavior and long term integrity.

To understand the mechanical implications of these microstructural heterogeneities we use X-ray microcomputed tomography (Lab and Synchrotron radiation) and DVC (digital volume correlation), aiming to characterize the in situ development of localization patterns and compaction bands in porous carbonates experiencing triaxial loadings.
