Collapse-upon-wetting behaviour of a volcanic soil

Experimental results of volumetric response of a volcanic soil were collected in standard oedometric tests, with the aim to evaluate the volumetric response of this soil when subjected to loading and wetting paths. Microstructural features of reconstituted ...

CNT and PDCs: A fruitful association? Study of a polycarbosilane–MWCNT composite

Jürgen Brugger, Rosario Maurizio Gullo, Jonas Grossenbacher

The effect of MWCNT introduction in a polycarbosilane based ceramic on its electrical properties is presented. The electrical conductivity of two MWCNT powders was measured under dynamic compaction up to 20 MPa when it reached 3–5 S/cm. The compaction beha ...

Microstructural influence on the scatter in the fatigue life of steel reinforcement bars

Alain Nussbaumer, Marina Rocha Pinto Portela Nunes

Fatigue damage accumulation and failure of steel reinforcement bars (rebars) is a stochastic process. Scatter can be influenced by the sensitivity of the short crack growth to the microstructural features, especially near the fatigue limit. This work inves ...

Toward Knowledge-Based Grain-Boundary Engineering of Transparent Alumina Combining Advanced TEM and Atomistic Modeling

Paul Bowen, Cécile Hébert, Marco Cantoni, Michael Stuer, Farhang Nabiei, Abhishek Tewari

Transition element dopants (e.g., Y, La) are commonly used as sintering aids in polycrystalline alumina ceramics, which segregate to the grain boundaries and control the grain-boundary mobility. However, due to the extremely thin (

Microstructural modelling of the elastic properties of tricalcium silicate pastes at early ages

Karen Scrivener, Shashank Bishnoi, Quang Huy Do

This paper describes the numerical calculation of elastic properties of a simulated microstructure of cement paste from very early age, when most previous models fail to give accurate results. The development of elastic properties of tricalcium silicate pa ...

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 ...

Investigation of microstructure and mechanical properties of W-Y and W-Y2O3 materials fabricated by powder metallurgy method

Nadine Baluc, Lyubomira Veleva

W-2Y, W-1Y(2)O(3) and W-2Y(2)O(3) materials have been fabricated using two different powder metallurgy methods. While W-2Y and W-1Y(2)O(3) have been fabricated using mechanical alloying and hot isostatic pressing (Hipping), W-2Y(2)O(3) has been fabricated ...

Micro-scale modeling of water diffusion in adhesive composite joints

Véronique Michaud, Luis Pablo Canal Casado

Water diffusion into composite adhesive joints was experimentally studied by means of gravimetric measurements in bond specimens. The main parameters controlling the diffusion in the bond components were obtained from water uptake experiments carried out i ...

Influence of microstructural heterogeneity on the scaling between flow stress and relative density in microcellular Al-4.5 %Cu

Andreas Mortensen, Yves Conde

We explore the influence of the metal microstructure on the compressive flow stress of replicated microcellular 400-mu m pore size Al-4.5 wt%Cu solidified at two different solidification cooling rates, in the as-cast and T6 conditions. It is found that the ...
