Fail-safe optimum cable system under cable breakage in cable-stayed bridges. Application to the Queensferry Crossing Bridge
(Elsevier, 2023)[Abstract:] This paper presents a methodology to optimize the cable system in cable-stayed bridges, whose main novelty is to take into account the accidental breakage of one cable within the design process. To this end, a ... -
Multi-bubble scheme and structural analysis of a hypersonic stratospheric flight vehicle
(Elsevier, 2022)[Abstract:] The STRATOFLY MR3 vehicle is the main objective of the STRATOFLY project, which aims to develop a hypersonic air breathing concept capable of covering antipodal routes in less than three hours. The aircraft ... -
Optimisation of Thin-Walled Hybrid Vertical Struts for Crashworthy Aircraft Designs
(Springer, 2020)[Abstract] This research concerns the crashworthiness enhancement of a model of a Boeing 737-200 fuselage section. Using a validated numerical specimen, four thin-walled crushable hybrid energy absorbers are added to the ... -
Reliability index based strategy for the probability-damage approach in fail-safe design optimization (β-PDFSO)
(Springer Nature, 2023)[Abstract:] This research proposes a new formulation for fail-safe size optimization, considering the probability of occurrence of each failure scenario and the random structural parameters as sources of uncertainty. ... -
Size and shape optimization of aluminum tubes with GFRP honeycomb reinforcements for crashworthy aircraft structures
(Elsevier, 2015)[Abstract:] Crashworthiness optimization of aircraft and automotive structures has become one the main research targets for their respective leading industries. The following research proposes a new design of an aircraft’s ... -
Square Cylinder Under Different Turbulent Intensity Conditions by Means of Small-Scale Turbulence
(WIT Press, 2021)[Abstract] The phenomenon of turbulence is present in almost every type of flow in practical applications. Depending on its level of intensity and length scale, it can modify both the aerodynamic and aeroelastic performance ... -
Testing and simulation of additively manufactured AlSi10Mg components under quasi-static loading
(Elsevier, 2020)[Abstract:] An experimental and numerical study on the quasi-static loading of AlSi10Mg square boxes produced by selective laser melting (SLM) was carried out. The goal was to evaluate the applicability of common finite ... -
Verification Approaches for the 3D Static LES Simulations of the Stonecutters Bridge Deck
(WIT Press, 2021)[Abstract] In computational fluid dynamics (CFD) simulations, verification is the process of identifying both the spatial and the temporal discretisations providing relatively insensitive model results. The underlying goal ... -
Wave Celerity in Hydraulic Transients Computation for CIPP-Rehabilitated Pipes
(WIT Press, 2020)[Abstract] Most of the water pipe infrastructure is outdated; therefore, frequent maintenance and repair works are required. To speed up the rehabilitation work and to have a more sustainable and efficient approach, ...
