Numerical analysis and discussion on the hot-spot stress concept applied to welded tubular KT jointsVieira Ávila, Bianca (author), Correia, J.A.F.O. (author), Carvalho, Hermes (author), Fantuzzi, Nicholas (author), De Jesus, Abílio (author), Berto, Filippo (author)Nominal stresses have been used for a long time for the assessment of fatigue resistance of welded joints, however, this approach has strong limitations since the definition of the nominal stress may be subjective for complex welded details and/or complex loading. On the other hand, the hot-spot stress approach has been proposed to overcome...journal article 2022

Ibraeva, Anna (author), Correia, Gonçalo (author), Silva, Cecília (author), Antunes, António Pais (author)Few studies have analyzed the mobility impacts of TOD using a longitudinal research approach, and even fewer incorporated origin–destination (OD) information in the analysis. In this paper, we examine the impacts of a metro system with TOD features on the share of car and bus trips using Metro do Porto as a case study. The application of an...journal article 2022

Pedrosa, Bruno (author), Correia, J.H.G. (author), Lesiuk, Grzegorz (author), Rebelo, Carlos (author), Veljkovic, M. (author)The UniGrow model is an analytical procedure to assess the fatigue crack growth based on elastic–plastic crack tip stresses and strains. The assumption is that fatigue crack growth (FCG) can be considered as a process of successive crack re-initiations resulting from material damage in the crack tip zone. The main parameters of this model are...journal article 2022

Calabrò, Giovanni (author), Le Pira, Michela (author), Giuffrida, Nadia (author), Inturri, Giuseppe (author), Ignaccolo, Matteo (author), Correia, Gonçalo (author)Feeder transport services are fundamental as first and last-mile connectors of mass rapid transit (MRT). They are especially beneficial in low-demand areas where private transport is usually the main transport mode. Besides, the rapid spread of new technologies such as vehicle automation and the shared mobility paradigm gave rise to new...journal article 2022
