The local strength of individual alumina particles

Andreas Mortensen, Goran Zagar, Václav Pejchal, Marta Fornabaio

We implement the C-shaped sample test method and micro-cantilever beam testing to measure the local strength of microscopic, low-aspect-ratio ceramic particles, namely high purity vapor grown a-alumina Sumicorundum (R) particles 15-30 mu m in diameter, kno ...

Phase assemblage of composite cements

Karen Scrivener, Mohsen Ben Haha, Pawel Tadeusz Durdzinski

The phase assemblage of binary Portland cements with 45 wt% replacement by calcareous fly ash and slag has been investigated by experiment, mass balance and thermodynamic simulations. The input for these calculations was based on clinker reaction measured ...

Small-scale metal castings, small-scale metal/transparent composite structures and process to produce same

Andreas Mortensen, Yves Bellouard, Raphaël Charvet, Cyril Dénéréaz

The method comprises at least the following steps: - exposing a substrate to focused laser irradiation at a preselected series of locations that trace a subset of the substrate volume that is connected to the surface of the substrate; some subsets of subst ...

Micro-mechanical finite element modeling of diagonal compression test for historical stone masonry structure

Jean-François Molinari, Katrin Beyer, Nicolas Richart, Shenghan Zhang, Seyedeh Mohadeseh Taheri Mousavi

Simulating the force-deformation behavior of stone masonry is a challenging issue. This paper contributes to this topic by developing a detailed micro-modeling method using extrinsic cohesive elements. To consider contact and friction, a new node-to-node a ...

Physical Phenomena in Dynamic Failure of Concrete at the Mesoscale

Okan Yilmaz

The aim of the present thesis is to model numerically the dynamic failure behavior of concrete at the mesoscale. Concrete is the world's most widely used construction material and the structures made of it are subjected to dynamic loads during their long s ...

Effect of an adhesive layer on the mode I delamination in unidirectional CFRP bonded joints

Nassima Nasri

Several toughening mechanisms, such as fibre bridging, can occur during delamination of fibre reinforced composites. In structures made of composite bonded joints, delamination can occur either in the composite or in the adhesive layer. In the first case c ...
