Laminated Metal Composites by Infiltration
Andreas Mortensen, Andreas Rossoll, Jérôme Krebs, Arda Cetin, Alexandre Durussel
We show that steel-magnesium alloy laminated metal composites (LMCs) can be produced by gas pressure infiltration of a liquid magnesium alloy between layers of stacked dimpled steel sheets. Resulting LMCs are amenable to subsequent warm rolling. The LMCs a ...
Springer US2011Hole and notch sensitivity of aluminium replicated foam
Andreas Mortensen, Etienne Combaz, Andreas Rossoll
The flow and failure behaviour of replicated pure aluminium foams in the presence of holes and notches is explored, varying the pore size and the notch depth or hole radius. Flat dog-bone tensile specimens containing a cylindrical hole, and cylindrical V-n ...
Elsevier2011Fracture of high volume fraction ceramic particle reinforced aluminium under multiaxial stress
Andreas Mortensen, Andreas Rossoll, Aude Hauert
Circumferentially notched cylindrical bars of high volume fraction Al2O3 particle reinforced aluminium are tested in tension to probe the role of tensile stress triaxiality on damage and failure of such materials. The transverse strain is monitored with a ...
Elsevier2010Ductile-to-brittle transition in tensile failure of particle reinforced metals
Andreas Mortensen, Andreas Rossoll, Aude Hauert
We present an analytical micromechanical model designed to simulate the tensile stress-strain behaviour and failure of damaging composites containing a high volume fraction of reinforcing particles. One internal damage micromechanism is considered, namely ...
Elsevier2009In situ flow stress of pure aluminium constrained by tightly packed alumina fibres
Andreas Mortensen, Ludger Weber, Andreas Rossoll, Benedikt Moser
The in situ matrix flow stress of continuous fibre-reinforced aluminium is measured in tension along the fibre axis. We use a new, tighter, estimate for the effect differential Poisson contraction between fibres and matrix and take into consideration nonli ...
Elsevier2009Tensile flow stress of ceramic particle-reinforced metal in the presence of particle cracking
Andreas Mortensen, Ludger Weber, Andreas Rossoll
A simplified model is proposed to quantity the effect of damage in the form of particle cracking on the elastic and plastic behaviour of particle-reinforced metal matrix composites under uniaxial tensile loading: cracked particles are simply replaced, in a ...
2008Measurement of damage evolution in continuous ceramic fibre-reinforced metals by acoustic emission
Andreas Mortensen, Ludger Weber, Andreas Rossoll, Benedikt Moser
Internal damage in uniaxial continuous alumina fibre-reinforced aluminium is measured by acoustic emission during tensile straining in the fibre direction. Over most of the loading history spatially uncorrelated fibre fragmentation occurs, consistent with ...
2008Damage and fracture of particle-reinforced metal matrix composites
Andreas Mortensen, Andreas Rossoll, Aude Hauert
Particle Reinforced Metal Matrix Composites (PRMMCs) are produced by high-pressure infiltration of ceramic particle beds. Matrix materials are either pure Al or Al-4,5%Cu, and the reinforcement is made either of angular or of polygonal alumina particles. T ...
2006Longitudinal deformation of fibre reinforced metals: Influence of fibre distribution on stiffness and flow stress
Andreas Mortensen, Andreas Rossoll, Benedikt Moser
A computational analysis of the longitudinal deformation of continuous fibre reinforced metals is presented. Elastic and elastic-plastic matrix behaviour are considered. Analytical approaches are confronted with finite element analyses (FEA) for varying fi ...
2005Structural metallic materials by infiltration
Andreas Mortensen, Ludger Weber, Andreas Rossoll, Randoald Müller, Jean-François Despois
An overview is presented of current research at EPFL on structural metallic materials produced by infiltration processing. The paper comprises a brief introduction to the infiltration process, then presents results on particle reinforced metals and open-ce ...
