Hydromechanical behavior of Tournemire argillites: Measurement of the poroelastic parameters and estimation of the intrinsic permeability by œdometric tests
Autor: E. Bemer, A. Giraud, A. Noiret, Richard Giot, F. Homand
Publikováno v: International Journal for Numerical and Analytical Methods in Geomechanics. 35:496-518
Knowledge of shale poromechanical behavior is proven to be essential for various environmental issues such as deep geological storage of CO2, high level radioactive waste storage, oil field abandonment and so forth… This paper sets out the key poin

Fully coupled poromechanical back analysis of the pulse test by inverse method
Autor: F. Homand, Théophile Guillon, A. Giraud, Richard Giot, Christophe Auvray
Publikováno v: International Journal for Numerical and Analytical Methods in Geomechanics. 35:329-359
In this paper, we investigate the pulse test, which is usually considered as efficient for measuring the permeability of weakly permeable porous media. The pulse is first analyzed and we show that it is a fully poromechanical coupled problem. Owing t

Experimental and numerical study of sub-critical crack growth in Meuse/Haute-Marne argillite
Autor: Christophe Auvray, Vincent Magnenet, A. Giraud, F. Homand
Publikováno v: Physics and Chemistry of the Earth, Parts A/B/C. 36:1867-1871
The evolution of crack growth velocity v vs. stress intensity factor K in Meuse/Haute-Marne argillite is experimentally investigated at different relative humidities. A new algorithm based on finite elements simulations aimed to process the measured

Parameter sensitivity analysis for a Drücker–Prager model following from numerical simulations of indentation tests
Autor: F. Homand, V. Magnenet, A. Giraud
Publikováno v: Computational Materials Science. 44:385-391
A parameter sensitivity analysis is carried out from numerical simulations of indention tests. The indented material obeys a simple Drucker–Prager behavior with no hardening rule, involving four material properties. For each of the parameters, the

Poromechanical Modelling and Inverse Approach of Drying Tests on Weakly Permeable Porous Rocks
Autor: F. Homand, A. Giraud, Richard Giot
Publikováno v: Transport in Porous Media. 76:45-66
The present paper deals with the determination of permeability in partially saturated conditions for weakly permeable porous rocks such as argillites or deep clayey formations. The level of permeability can be obtained via the measurements of transie
