High temperature mechanical spectroscopy of yttria stabilized zirconia reinforced with carbon nanotubes

Daniele Mari, Robert Schaller, Mehdi Mazaheri

High temperature mechanical properties of zirconia reinforced with carbon-nanotubes (CNTs) are studied by mechanical spectroscopy. CNTs limit zirconia grain-boundary sliding (GBS) and consequently deformation. Concurrent grain-growth and plastic deformatio ...

In 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 ...

Ceramic particles and layers for functional application

Heinrich Hofmann

Besides 'bulk' structural and functional ceramic, a third interesting group of inorganic or ceramic materials exists: particles used for medical applications like contrast agent as building blocks for photonic crystals, as thin or thick layers with control ...

Mechanical spectroscopy of interface stress relaxation in magnesium matrix composites

Abu Salek Md. Fahim Chowdhury

Magnesium matrix composites made of pure (99.98%) magnesium reinforced with long carbon (Mg/C) and stainless steel (Mg/steel) fibers were processed by low pressure infiltration method. Mg/C composites were then oriented from the crystallographic point of v ...

Damage propagation and fracture in highly reinforced particulate metal matrix composites

Aude Hauert

This study contributes to our understanding of the damage evolution and fracture behaviour of two-phase materials that combine brittle particles with a ductile matrix. We focus on model composites roughly half-ceramic/half-metal that are produced in-house ...

Correlation of microstructural and mechanical properties in particle reinforced lead-free solders

Venkatesh Sivasubramaniam

Solders are widely used as interconnect material for the electronic industry. The solder interconnect provides both electrical contact and mechanical connection between the integrated circuit devices and their substrate. Thus solders with good reliability ...

Micromechanics and damping properties of composites integrating shear thickening fluids

Pierre-Etienne Bourban, Razvan Cristian Neagu

Damping is an important parameter for vibration control, noise reduction, fatigue endurance or impact resistance of composite materials. In this study, a micromechanical model was used to predict the damping of a composite material containing shear thicken ...

Ductile-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 ...

Numerical simulation of solidification kinetics in A356/SiCp composites for assessment of as-cast particle distribution

Arda Cetin

The present work is aimed at studying the effect of solidification rate on reinforcement clustering in particle reinforced metal matrix composites (PMMCs) through numerical simulations and experimental studies. A macrotransport-solidification kinetics (MTS ...
