Advanced polymer matrix composites are gaining the market in their way due to exceptional specific stiffness, strength, fatigue, and corrosion resistance field of Auto-Tech, Aero-Tech, Biotech, etc. However, lack ductility catastrophic failure has limited application these areas. Hence there is a need explore means protocols for designing reduced factor safety with high-performance toughened co...

This study was performed in the framework of a research program focused in the development of high tenacity polypropylene (PP) fibres for the reinforcement of cementitious composites. Precedent reports have demonstrated how micromechanical modelling was used to attain significant improvements with respect to the macroscopic properties of cementitious composites. These improvements have been bas...

The simulation of damage and failure in short fiber reinforced composites like high performance hybrid-fiber reinforced cement composites is still a challenging task, due to the richness of failure mechanisms introduced by fibers on the mesoscale of the material. Randomly oriented, hooked steel fibers, like the Baekaert Dramix® fibers, sustainable modify the macroscopic failure behavior of the ...

Seismic pressures on a reinforced concrete moment-resisting structure are known to create critical and essential regions at the beam-column joints. Beam-column junctions microcosm of whole structure, therefore brittle behavior these points predicts action. Ductile joints ductile Under influence seismic forces, between RC beams columns exposed high shear stresses. Learn more about performance fi...

This paper reports ductile or partial ductile mode machining of silicon, glass and some advanced ceramics. Results are presented using scanning electron micrographs of the machined surfaces. Grinding and lapping operations using inexpensive machine tools could produce ductile streaks on surfaces of these brittle materials under good conditions. Manufacture of spherical glass lenses by the fract...

In this paper, the compressive behavior of fiber-reinforced concrete with end-hooked steel fibers has been investigated through a uniaxial compression test in which the variables were concrete compressive strength, fiber volumetric ratio, and fiber aspect ratio (length to diameter). In order to minimize the effect of specimen size on fiber distribution, 48 cylinder specimens 150 mm in diameter ...
