Effective mechanical behavior of sandwich beams under uncoupled bending and tor...
Silva, Hugo Miguel Andrade Lopes Figueiredo da; Meireles, José F."International Conference on Applied Mechanics and Mechanical Automation (AMMA 2014)". Serie - Applied mechanics and materials, vol. 590 ; Sandwich geometries, mainly panels and beams are widely used in several transportation industries, namely aerospace, aeronautic and automotive. Sandwich geometries are known for their advantages in structural applications: high specific stiffness, low weight, and possibilit...
Velocity and structural model of the Lower Tagus Basin according to the study o...
Torres, Ricardo; Furtado, Augusto; Silva, Hugo; Borges, JF; Caldeira, Bento; Bezzeghoud, Mourad; Carvalho, JoãoAlong his history the Lower Tagus Valley (LTV) region was shaken by several earthquakes, some of them produced in large ruptures of offshore structures located southwest of the Portuguese coastline. Among these is the Lisbon earthquake of 1 November 1755 (M∼8.5-8.7), and other moderates earthquakes that were produced by local sources such as the 1344 (M6.0), 1531 (M7.1) and 1909 (M6.0) earthquakes. Previous sim...
Seismic ground motion scenarios in Lower Tagus Valley Basin
Borges, J. F.; Torres, Ricardo; Furtado, Augusto; Silva, Hugo; Bezzeghoud, Mourad; Caldeira, Bento; Pinto, CarlosThroughout its history the Lower Tagus Valley (LTV) has been struck by several earthquakes which produced important material damage and loss of lives: The 1st of November 1755 Lisbon earthquake and the 1969 earthquake (Mw=7.3), located in the SW Iberia Margin and the 1344, 1531 and 1909 (M= 6 to 7) with epicenter located inside the LTV basin. Since this region is the most highly populated region in Portugal, it...

Genomic diversity of drug-resistant mycobacterium tuberculosis isolates in Lisb...
Perdigão, João; Silva, Hugo; Machado, Diana; Macedo, Rita; Maltez, Fernando; Silva, Carla; Jordão, Luisa; Couto, Isabel; Mallard, Kim; Coll, FrancescMultidrug- (MDR) and extensively drug resistant (XDR) tuberculosis (TB) present a challenge to disease control and elimination goals. Lisbon, Portugal, has a high TB incidence rate and, unusual and successful XDR-TB strains that are found in circulation for almost two decades. In the present study, 56 Mycobacterium tuberculosis isolates, mostly recovered in Lisbon, were genotyped by 24-loci Mycobacterial Inters...
Numerical study on the sensitivity analysis for strenght and stiffness of regul...
Silva, Hugo Miguel Andrade Lopes Figueiredo da; Peixinho, Nuno; Silva, Filipe SamuelThe aim of this study is to present a sensitivity analysis of geometric variables on the mechanical behavior of regular cellular solids. The cellular solids studied are named “spherical” and “elliptical”, if there is part of an empty sphere inside or if there is part of an empty revolved ellipse, respectively. Pure loads are applied separately, namely compression and shear, in order to study the influence of th...
Determination of material/geometry of the section most adequate for a static lo...
Silva, Hugo Miguel Andrade Lopes Figueiredo da; Meireles, José F.The acceleration of industrial machines mobile parts has been increasing over the last few years, due to the need of higher production in a short period of time. The machines were dimensioned for a lower value of acceleration, which means there is not enough rigidity for the correct operation at much higher accelerations. Nowadays, the accelerations can be near 12 times the acceleration of gravity. There is the...
Utilização de nanopartículas de TIO2 para o desenvolvimento de pavimentos rodov...
Carneiro, Joaquim A. O.; Freitas, Elisabete F.; Teixeira, Vasco M. P.; Fernandes, Filipa; Silva, Hugo Manuel Ribeiro Dias da; Oliveira, Joel; Nunes, C.A utilização de nanomateriais na indústria de construção rodoviária representa uma opção estrategicamente inovadora que visa a modificação dos materiais convencionais. Neste âmbito, dotar a superfície dos pavimentos rodoviários de capacidade fotocatalítica contribuirá para efetuar a despoluição do ar e a redução da sujidade adsorvida nestas superfícies, aumentando a segurança rodoviária uma vez que minimiza a p...
