Microscopic strength of silicon particles in an aluminium–silicon alloy

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller, Marta Fornabaio

A microscopic three-point bending test that measures the strength of faceted particles of high aspect ratio is developed and used to probe individual coarsened plate-like silicon particles extracted from the eutectic Al-12.6%Si alloy. Focused ion beam mill ...

The negative piezoelectric effect of the ferroelectric polymer poly(vinylidene fluoride)

Dragan Damjanovic

Piezoelectricity describes interconversion between electrical charge and mechanical strain. As expected for lattice ions displaced in an electric field, the proportionality constant is positive for all piezoelectric materials. The exceptions are poly(vinyl ...

Hexagonal OsB2: Sintering, microstructure and mechanical properties

Martin Guillermo Mueller, Nina Orlovskaya

The metastable high pressure ReB2-type hexagonal OsB2 bulk ceramics was produced by spark plasma sintering. The phase composition, microstructure, and mechanical behavior of the sintered OsB2 were studied by X-ray diffraction, optical microscopy, TEM, SEM, ...

Fatigue behaviour prediction of steel reinforcement bars using an adapted Navarro and De Los Rios model

Alain Nussbaumer, Marina Rocha Pinto Portela Nunes

Fatigue cracks tend to initiate on the rebar surface and therefore, the surface conditions may control their fatigue behaviour. This study investigates the influence of surface microstructure and roughness dispersion on the scatter and fatigue life of hot ...

Effect of treatment on the microstructural characteristics of bio-improved sand

Lyesse Laloui, Dimitrios Terzis

Bio-chemical processes have recently become the core of several studies in the geoengineering field, where the emphasis is placed on new and emerging applications. Microbially Induced Calcite Precipitation has been introduced as an alternative cementation ...

Accelerated Microstructure Imaging via Convex Optimization (AMICO) in crossing fibers

Jean-Philippe Thiran, Yves Wiaux, Erick Jorge Canales Rodriguez, Alessandro Daducci, Anna Auria Rasclosa, Tim Bjørn Dyrby

Mapping the local microstructure properties of the tissue in the brain is crucial to understand any pathological condition from a biological perspective. In recent years, microstructure-imaging techniques aimed at extracting such precious information by us ...

Dynamic crack propagation in a heterogeneous ceramic microstructure, insights from a cohesive model

Jean-François Molinari, Nicolas Richart, Seyedeh Mohadeseh Taheri Mousavi, Cyprien Wolff

A 2D plane-strain dynamically propagating crack under tensile loading is simulated with cohesive elements. Information of the main crack is extracted from a diffuse crack network with the use of graph properties. Micro-transgranular fracture properties are ...

Dynamic crack propagation in a heterogeneous ceramic microstructure, insights from a cohesive model

Seyedeh Mohadeseh Taheri Mousavi

Silicon nitride is a widely used industrial ceramic, specifically for dynamic loading applications because of its special mechanical and material properties. The investigation of the underlying mechanisms which lead to these properties is experimentally ch ...
