Compaction of highly porous granular matter by impacts on a hard wall
(American Physical Society, 2015-04)
Using a granular-mechanics code, we study the impact of a highly porous granular body on a hard wall. The projectile consists of monodisperse adhesive micrometer-sized silica grains. For the impact velocities studied, ...
Mechanical properties of HIPS/sugarcane bagasse fiber composites after accelerated weathering
(Elsevier B.V., 2011-01-01)
The effect of accelerated weathering on the visual appearance and on mechanical properties of high impact polystyrene (HIPS) as well as HIPS reinforced with mercerized and bleached sugarcane bagasse fibers composites are ...

A novel up-converting mechanism based on double impact for non-linear piezoelectric energy harvesting
(IOP Publishing, 2020-11-01)
In this paper we show the importance of double impact in an up-converting mechanism by usinga resonant low-frequency driving beam across a high-frequency piezoelectric beam, to enhancethe electrical output power in a ...
Mortar added by tyre rubber residues: Characterisation in fresh and hardened state
(2004-12-01)
Due to the progressive increase of vehicles, the number of used tires is globally one of the serious environmental problems faced now. Therefore, several researches have being developed for its reuse. The use of tires' ...
