Multiaxial Yield and Fracture of Replicated Microcellular Aluminium

This work addresses the behaviour of replicated microcellular pure aluminium under multiaxial stress states and in the presence of stress and strain localization sites. Processing of the foam was conducted in-house, using the replication process. The main ...

Plasticity and geophysical flows: A review

Christophe Ancey

The objective of this review is to examine how the concept of plasticity is used in geophysical fluid dynamics. Rapid mass movements such as snow avalanches or debris flows involve slurries of solid particles (ice, boulder, clay, etc.) within an interstiti ...

Structure et mécanismes de microdéformation de polymethylmethacrylates renforcés au choc

Laure Dupuits Lalande

Polymethylmethacrylate (PMMA) is used in many applications requiring good optical properties, resistance to ageing and resistance to UV irradiation, in spite of its relatively poor mechanical response to impact loading. In order to extend the range of appl ...

Unified stress framework for modelling unsaturated subsoil behaviour

Lyesse Laloui, Mathieu Nuth

Traffic loads combined with moisture variations are the most harmful for road structures. Even if the pavement is assumed to have an elastic behaviour, the partially saturated subsoil can present irreversible strains that endanger the integrity of the road ...

Yodel: A Yield Stress Model for Suspensions

Paul Bowen

A model for the yield stress of particulate suspensions is presented that incorporates microstructural parameters taking into account volume fraction of solids, particle size, particle size distribution, maximum packing, percolation threshold, and interpar ...
