Computational Techniques for Novel Design of Long-Span Bridges Considering Aeroelastic Phenomena
(ASCE, 2020)
[Abstract] Optimization techniques have demonstrated their capability to obtain economic and sustainable designs while meeting the performance and safety requirements in a number of engineering disciplines. In the bridge ...
Bridge deck flutter derivatives: Efficient numerical evaluation exploiting their interdependence
(Elsevier, 2015-01)
Increasing the efficiency in the process to numerically compute the flutter derivatives of bridge deck sections is desirable to advance the application of CFD based aerodynamic design in industrial projects. In this article, ...
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 ...
An Open-Source Framework for Aircraft Damage Simulation in Engine Failure Events
(Elsevier, 2022)
[Abstract] The aerospace industry demands designs capable of withstanding the simultaneous collapse of several structural elements. Examples of this failure scenario are propeller blade or uncontained engine rotor failures, ...
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. ...
Experiences on structural optimization under uncertainty in aerospace components
(WIT Press, 2018)
[Abstract:] Nondeterministic optimization methods have been studied in depth from an academy and industrial point of view. The main drawback when implementing probabilistic optimization methods to complex structures is the ...
Optimum design of cable-stayed bridges considering cable failure
(WIT Press, 2022)
[Abstract:] A methodology to obtain the minimum weight of cables in cable-stayed bridges when a cable fails has been developed. To this end, a multi-model strategy is proposed that takes into account design constraints in ...
Aerostructural Optimization of Long Span Bridges: Current Advances and Challenges
(ASCE, 2020)
[Abstract] This paper describes the evolution of deck shape of long span bridges since the Tacoma Narrows collapse trying to avoid undesirable aerodynamic behavior under wind flow and the trend in the last decades to ...
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 ...
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 ...
