A transfer function method to predict building vibration and its application to railway defects
(Elsevier, 2020-01-30)
This work presents a simplified method to evaluate building shaking due to arbitrary base excitations, and an example application to railway problems. The model requires minimal computational effort and can be applied to ...

On the vertical coupling effect of ballasted tracks in multi–span simply–supported railway bridges under operating conditions
(Taylor & Francis Group, 2022)
This contribution investigates the vertical coupling exerted by ballasted tracks on the vertical response of bridges composed either of (i) several successive simply-supported spans with weak coupling between them due to ...

Experimental and numerical evaluation of the wind load on the 516 Arouca pedestrian suspension bridge
(Elsevier B.V., 2022-01)
The present work analyses the wind load effects on the 516 Arouca bridge, the world's longest pedestrian suspension bridge in 2020. Computational fluid dynamics (CFD) was used to model a range of wind angles of attack ...

Numerical analysis of the crack paths produced by fibre–matrix interface failure in cross-ply LFRP laminates
(Elsevier, 2022-03)
The so-called matrix failure, also named inter-fibre failure, is one of the main failure mechanisms in long fibre reinforced polymers (LFRPs). This mechanism is characterized by the debonding of some fibres when transverse ...

Locking treatment of penalty-based gradient-enhanced damage formulation for failure of compressible and nearly incompressible hyperelastic materials
(Institute of Electrical and Electronics Engineers, 2023-03)
Soft materials are of major interest for biomechanics applications due to their high deformability and susceptibility to experience damage events under different loading scenarios. The present study is concerned with ...

Residual Tensile Strength of Multi-Impacted Woven Glass Fibre-Reinforced Polymer Composites
(INEGI / FEUP (Faculty of Engineering of University of Porto), 2023-07)
The effect of multiple low-velocity impacts on the tensile strength of E-glass/epoxy woven fabric composite laminates was studied. For this purpose, specimens with a lay-up sequence of [0,90]10 were considered, which were ...
