Hot tearing is one of the most severe defects observed in castings, e.g. in billets or sheet ingots of aluminum alloys produced by DC casting. It is due to both tensile strains and a lack of interdendritic feeding in the mushy zone. In order to predict thi ...
The objective of this review is to examine how the concept of plasticity is used in geophysical fluid dynamics. Rapid mass movements such as snow avalanches or debris flows involve slurries of solid particles (ice, boulder, clay, etc.) within an interstiti ...
The aim of this thesis is to assess the feasibility of integrating nanoparticles into glass fiber (GF) reinforced isotactic polypropylene (iPP) composites via existing thermoplastic processing routes, and to investigate whether this results in significant ...
The aim of this thesis has been to assess the potential of branched polymers as novel exfoliants for layered silicates and their application in polyurethanes. Three different types of –OH functional branched polymers have been studied: dendrimers, hyperbra ...
In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. These solicitations affect the bituminous layers that can quickly attain their permanent deformation limit resistance. This phenomenon can lead ...
The asphalt rubber blends design is an empirical procedure and is quite sensitive to the variability of the components properties. A better understanding of the physical phenomenon involved during the curing process is a prerequisite step to propose a rati ...
This communication concerns analysis of the behavior of flexible pavements using an elastic-viscoplastic constitutive relation for the asphalt concrete. The numerical model takes into consideration the influence of the temperature on the behavior of the as ...
Pavement rutting not only decreases the road service life but also creates a danger for the security of road users. In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. It is well known that the in ...
The increasing needs of extending the lifetime in high-technology fields, such as space and aerospace, rail transport and naval systems, require quality enhancing of the composite materials either from a processing standing point or in the sense of resista ...
Temperature variations are particularly harmful to wearing courses with asphalt mixture. During wintertime, and especially, at very low temperatures, a surface cracking may appear and propagate more or less rapidly. An experimental investigation has been c ...
