The extremely low permeability of Ultra-High Performance Fibre Reinforced Concretes (UHPFRC)associated to their outstanding mechanical properties make them especially suitable to locally "harden" reinforced concrete structures in critical zones subjected t ...
The constant improvement of polymer composite materials has allowed their integration in many industrial fields where their mechanical and chemical properties are apparently attractive. Mixed metal-composite insulators are now increasingly used for high vo ...
Force and pressure sensors based on the piezoresistive properties of thick- film resistors have recently found wide application due to their low cost, reliability, and relatively good precision. Achieving high elastic mechanical strains is important to max ...
The mechanisms of deformation and failure in Al-Si nanocomposites, formed by adding Si particles to Al nanocrystalline materials, are investigated using molecular dynamics. The deformation and fracture mechanisms are found to be different in the Al-Si comp ...
Molecular dynamics is used to examine the deformation and failure of Al-Si interfaces and of nanocomposites consisting of Al and Si nanograins loaded in tension. The modified embedded atom method, is used to describe the forces and energies in the system a ...
A model for predicting composite material strength degradation under elevated and high temperatures is proposed. This model is based on the morphology of the mixture of materials in different states. The degradation of resin-dominated shear strength can be ...
Diamond reinforced metals with a diamond content of 55-60 vol.% were made by gas driven liquid metal infiltration. They were characterized with regard to their stiffness, strength and fracture toughness as a function of diamond particle size and matrix all ...
The constitutive response of a Sigma9(221) symmetric tilt grain boundary in copper is investigated with an atomistic quasicontinuum method under tension and shear. The maximum strength is found to change with the deformation mode triggered at the interface ...
Three different approaches for metal to ceramic brazing are compared using the example of Si3N4/TiN-steel joints: the use of an active filler metal (single layer brazing system), the metallisation of the ceramic and brazing with a non active filler (two-la ...
Ultra high performance fibre reinforced concrete (UHPFRC) early age viscoelastic behaviour under tension was investigated. The tests results showed a high creep potential due to the high volume paste (88%). This result is of major importance because the vi ...
