    The aim of this paper is to present a Lagrangian formulation for thermo-coupled fluid–structure interaction (FSI) problems and to show its applicability to the simulation of hypothetical scenarios of a nuclear core melt ...

  • Novel seismic design solution for underground structures. Case study of a 2-story 3-bay subway station 

    Bu, Xiangbo; Ledesma Villalba, Alberto; López Almansa, Francisco (Elsevier, 2022-02)
    Article
    Open Access
    This paper proposes an innovative seismic design approach for shallow rectangular cut-and-cover underground subway or railway stations. The traditional approach is to design rigid frame-like structures by connecting rigidly ...

  • Factors influencing Safety on Construction Projects (fSCPs): types and categories 

    Muñoz La Rivera, Felipe; Mora Serrano, Javier; Oñate Ibáñez de Navarra, Eugenio (2021-10)
    Article
    Open Access
    Due to the fact of activity, environment and work dynamics, the construction industry is characterised by high accident rates. Different initiatives have emerged to reduce these figures, which focus on using new methodologies ...

    We present a stable finite element formulation for the shallow water equations using the finite increment calculus (FIC) procedure. This research is focused on the stability properties of the FIC technique and uses linear ...

  • A simple and effective 1D-element discrete-based method for computational bone remodeling 

    Quexada Rodríguez, Diego; Márquez Flórez, Kalenia; Cerrolaza Rivas, Miguel Enrique; Duque Daza, Carlos; Trabelsi, Olfa; Velasco, M. A.; Ramtani, Salah; Ho-Ba-Tho, Marie Christine; Garzon Alvarado, D. A. (Gordon and Breach Science Publishers, 2022-02)
    Article
    Open Access
    In-silico models applied to bone remodeling are widely used to investigate bone mechanics, bone diseases, bone-implant interactions, and also the effect of treatments of bone pathologies. This paper proposes a new methodology ...

  • Study of the aerodynamic forces on a simplified shape X-43 aircraft under supersonic conditions, design optimization 

    Carós Roca, Lidia; Jané Ippel, Christian; Coma Company, Martí; Pons Prats, Jordi; Bergadà Granyó, Josep Maria (2020-01-22)
    Article
    Open Access
    The paper focuses on the shape optimization, based on the resultant aerodynamic forces, of a simplified X-43 aircraft. The equations of oblique shock waves and Prandtl-Meyer expansion waves, along with the improvement of ...

  • Comparing hysteretic energy and ductility uniform annual failure rate spectra for traditional and a spectral shape-based intensity measure
