Impact response of different materials for sports mouthguards
Reis, P. N. B.; Amaro, Ana Paula; Neto, Maria Augusta; Messias, Ana; Ramos, João Carlos; Moreira, MariaUp to this moment, there is no guideline regarding the materials to produce mouthguards. The most used is Ethylene-Vinyl Acetate (EVA). Studies indicate that laminating EVA sheets with rigid components could increase the protection capacities of the mouthguards. On the other hand, other studies suggest that only replacement of the material within its structure can increase energy absorption. Therefore, this wor...
Comparison of mechanical performance between friction-stir spot welded and adhe...
Reis, Paulo N. B.; Amaro, Ana Paula; Loureiro, AltinoThe main goal of this study is to compare the morphology and mechanical strength of friction stir spot welded (FSSW) joints and adhesive bonded stepped joints. The welded joints were produced by friction stir spot welding, while the adhesive bonded ones used an Araldite 420 A/B adhesive. All joints were subjected to morphology and microstructure analyses, microhardness tests, tensile-shear tests and local strai...
