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 ...
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 ...
Besides the 50s revolution of the use of adhesives in the new construction in the works of strengthening and repair of different structural elements, adhesives were extensively used in bridges for a long time. Different applications on bridges were carried ...
We have studied the retention indices of 127 volatile substances on a C-78-paraffin and on its seven nearly isochor and isomorphous polar derivatives over a temperature range of 90-210 A degrees C. The retention index of a substance on the C-78 paraffin ha ...
Al-6.4 wt% Ni open-cell foams produced by replication are tested in compression and in tension at room temperature and creep tested in tension at 450C. The mechanical behaviour of this foam at room temperature is consistent with that observed for other ope ...
Bamboo – identified as a Non Timber Forest Product (NTFP) – offering optimal mechanical properties for construction purposes, and at the same time little studied among contemporary building materials, is paradoxically most used in precarious housing. The u ...
Hot tearing, a severe defect occurring during solidification is the conjunction of tensile stresses which are transmitted to the mushy zone by the coherent solid underneath and of insufficient liquid feeding to compensate for the volumetric change. The RDG ...

Ultra High Performance Fiber Reinforced Concretes (UHPFRC) present outstanding mechanical properties and a very low permeability. Those characteristics make them very attractive for the rehabilitation of existing structures and the conception of new struct ...
Prediction error identification requires that data be informative with respect to the chosen model structure. Whereas sufficient conditions for informative experiments have been available for a long time, there were surprisingly no results of necessary and ...
The origin of intragranular variations of the crystallographic orientation in hot-dip Al-Zn-Si coatings is discussed based on new experimental results and modelling. The solidification microstructure in as-received 55Al-43.4Zn-l.6Si (in wt.%) coatings depo ...
