Mapping Spatial Distribution of Pores in an Additively Manufactured Gold Alloy Using Neutron Microtomography

Roland Logé, Jamasp Jhabvala, Markus Strobl, Hossein Ghasemi Tabasi, Michaël Meyer

A crucial criterion for the quality of the additively manufactured parts is the porosity content for achieving an acceptable final relative density. In addition, for jewelry applications, visible pores are unacceptable at or in the vicinity of the surface. ...

Universal features of anticrack nucleation in porous solids

Johan Alexandre Philippe Gaume, Henning Löwe, Jonas Ritter

Characterizing the nucleation of anticracks in porous materials under compression is a great challenge and has been the subject of several investigationsin different fields, from earthquake science, rock mechanics to avalanche research[1]. Yet, the conditi ...

Impact of CO2 injection on the hydro-mechanical behaviour of a clay-rich caprock

Lyesse Laloui, Valentina Favero

The safe storage of CO2 in deep reservoir units requires an efficient sealing of the overlaying caprock. The acidic environment caused by the dissolution of CO2 into the pore fluid can induce changes in the microstructure of the material over the long term ...

Multiresponse modeling of variably saturated flow and isotope tracer transport for a hillslope experiment at the Landscape Evolution Observatory

Damiano Pasetto

This paper explores the challenges of model parameterization and process representation when simulating multiple hydrologic responses from a highly controlled unsaturated flow and transport experiment with a physically based model. The experiment, conducte ...

Water retention behavior of deformable soils-experiment and modeling

Lyesse Laloui, Alessio Ferrari, Mathieu Nuth, Simon Salager

The paper presents an experimental and modelling approach for the soil water retention behaviour of two deformable soils. The objective is to investigate the physical mechanisms that govern the soil water retention properties and to propose a constitutive ...

Characterization of gas flow through low-permeability claystone: laboratory experiments and two-phase flow analyses

Alessio Ferrari

For the characterization of gas migration through a low-permeability clay host rock for deep underground repositories, a comprehensive understanding of the relevant phenomena of gas and fluid flow through low-permeability clay is required. The National Coo ...

The Pore Structure Of Compacted And Partly Saturated Mx-80 Bentonite At Different Dry Densities

Alessio Ferrari, Ali Seiphoori

Compacted MX-80 bentonite is a potential backfill material in radioactive-waste repositories. Pore space in MX-80 has been the subject of considerable debate. 3D reconstructions of the pore space based on tomographic methods could provide new insights into ...

Characterization of THM Behaviour of Compacted MX-80 Granular Bentonite Using an Advanced Double-wall Triaxial Cell

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

This paper aims at characterization of thermo-hydro-mechanical behaviour of MX-80 granular bentonite obtained from an innovative double-cell triaxial system. The system has been mainly developed to perform suction controlled tests on unsaturated geomateria ...

Multi-Scale Approach to Cracking Criteria for Drying Silty Soils

Lyesse Laloui, Mohammad Monfared

Cracking is a most unwanted development in soil structures undergoing periodic drying. Desiccation cracking arises in the apparent absence of external forces. Hence, either an internal, self equilibrated stress pattern resulting from kinematic incompatibil ...
