Frictional Properties of Opalinus Clay

Marie Estelle Solange Violay, Luis Felipe Orellana Espinoza

Opalinus Clay (OPA) is the host rock being proposed in Switzerland for disposal of high-level radioactive waste. The stability of fault zones within this formation is a key issue to ensure long-term performance of the repository. To understand the friction ...

Numerical modeling of fluid-structure interaction in arteries with anisotropic polyconvex hyperelastic and anisotropic viscoelastic material models at finite strains

Alfio Quarteroni, Simone Deparis, Davide Forti

The accurate prediction of transmural stresses in arterial walls requires on the one hand robust and efficient numerical schemes for the solution of boundary value problems including fluid-structure interactions and on the other hand the use of a material ...

Particle Size Segregation in Dense Granular Flows

Kasper van der Vaart

Flows of granular materials widely occur in many industrial and natural environments. Particle-size segregation---the separation of grains of different sizes during flow---plays a crucial role in the behaviour of such flows. In spite of considerable effort ...

Multiphysical phenomena and mechanisms involved with energy piles

Lyesse Laloui, Alessandro Francesco Rotta Loria

This study proposes an analysis of the multiphysical phenomena and mechanisms governing the thermo-mechanical behaviour of energy piles. The analysis is based on the results of a series of full-scale in-situ tests, laboratory experiments and numerical anal ...

Integrated maintenance model for heavy haul tracks

José João Pires De Oliveira Filho

Due to the accumulation of traffic, the railway components are affected by the induced stresses. As a result, the geometry of the railways is degraded over time. The degradation occurs either through the partial loss of the track's geometry or through the ...

Pressure-Driven Suspension Flow near Jamming

Brice Tanguy Alphonse Lecampion, Dmitriy Garagash

We report here magnetic resonance imaging measurements performed on suspensions with a bulk solid volume fraction (φ0) up to 0.55 flowing in a pipe. We visualize and quantify spatial distributions of φ and velocity across the pipe at different axial positi ...

Modeling of percolation of globular-equiaxed grains in Al-Cu alloys

Michel Rappaz, Jean-Luc Desbiolles, Christophe Mondoux

A new mesoscopic model able to describe percolation of globular-equiaxed grains, highly relevant for hot tearing formation in castings, has been developed. This model is inspired from the granular model of Sistaninia et al. [1-5] that considers polyhedral ...

Mesoscopic Modeling and Experimental Investigations of the Last-Stage Solidification of Globular-Equiaxed Grains in Metallic Alloys

Christophe Mondoux

Hot tearing is a major defect of solidification processes and welding. It occurs in metallic alloys while they are in the semi-solid state and is caused by a lack of liquid feeding in the mushy zone to compensate solid network openings due to tensile and s ...
