  • The Shifted Boundary Method for contact problems 

    Li, Kangan; Gorgi, Andrea; Rossi, Riccardo; Scovazzi, Guglielmo (Elsevier, 2025-05)
    Article
    Restricted access - publisher's policy
    We propose an embedded algorithm for contact mechanics based on the Shifted Boundary Method. The contact conditions are applied on a surrogate contact surface in proximity of the true contact surface and Taylor expansions ...
  • Damage and failure modeling of composite material structures using the Pam-Crash code 

    Martín Santos, Eduardo; Barbu, Lucia Gratiela; Cruz, Pablo (Multidisciplinary Digital Publishing Institute (MDPI), 2024-12)
    Article
    Open Access
    Simulating composite material structures requires complex constitutive models, which normally require fine meshes to obtain an accurate prediction of their behavior. Pam-Crash software has been used for several years in ...
  • Global length and overhang control for level set and density approaches via perimeter minimization 

    Torres Lerma, Jose Antonio; Otero Gruer, Fermín Enrique; Ferrer Ferré, Àlex (John Wiley & sons, 2025-01-20)
    Article
    Restricted access - publisher's policy
    Topology optimization is probably one of the most efficient techniques for structural design. However, running topology optimization without geometry control provides complex designs, which often are manufactured with ...
  • Considering creep in rock tunnelling with a combined support system: theoretical solutions and machine-learning solver 

    Song, Fei; Wang, Huaning; Shang, Chengshun; Rodríguez Dono, Alfonso; Wang, Ertai; Gui, Jingyun; Alejano, Leandro R. (2024-11)
    Article
    Restricted access - publisher's policy
    This study provides an alternative theoretical approach to analyse the mechanical behaviour of tunnels excavated in time-dependent geomaterials, considering the sequential excavation of tunnels and installation of rockbolts ...
  • Embedded technology for enhanced modeling of Friction Stir Welding processes 

    Venghaus, Henning; Chiumenti, Michele; Baiges Aznar, Joan; Juhre, Daniel; Dialamishabankareh, Narges (Elsevier, 2025-02)
    Article
    Open Access
    Friction Stir Welding (FSW) is a solid-state joining process that has several benefits over conventional welding techniques. A major challenge is its high sensitivity to process parameters such as advancing and rotational ...
  • Study on rheological properties of composite propellant slurry in the mixing process by using experimental and numerical simulation 

    Guo, Zhiming; Fu, Xiaolong; Rossi, Riccardo (Royal Society of Chemistry (RSC), 2024-12)
    Article
    Open Access
    Researchers have extensively focused on the safety of the solid propellant preparation process, particularly the mixing process that was deemed critical for the safety of the entire procedure. Herein, the rheological curves ...
  • Fatigue delamination damage analysis in composite materials through a rule of mixtures approach 

    Taherzadeh Fard, Alireza; Jiménez Reyes, Sergio; Cornejo Velázquez, Alejandro; Oñate Ibáñez de Navarra, Eugenio; Barbu, Lucia Gratiela (2025-01)
    Article
    Open Access
    The present study investigates delamination damage initiation and propagation within a homogenization theory of mixtures, using the concept of virtual layers and virtual interfaces. It eliminates spatial discretization of ...
  • Fire performance of a new shear transfer system for CFST columns 

    Ebrahimi, Minoo; Marimón Carvajal, Federico; Soltanalipour, Milad; Ferrer Ballester, Miquel; Álvarez, Felipe; Alonso, Mar; del Coz Díaz, Juan José; Martínez Martínez, Juan Enrique (Zenodo, 2024)
    Conference report
    Open Access
    The conventional shear transfer elements applied in beam-to-CFST columns include shear studs, steel bars, angles, internal rings, and steel plates. The new UPCCFST system is comparatively easier to execute because the shear ...
  • Dynamic analysis with point-masses of perforated pallet rack structural members by means of the Generalized Beam Theory 

    López Rull, Ignasi; Bonada Bo, Jordi; Bové Tous, Oriol; Casafont Ribera, Miguel (2024-06)
    Article
    Open Access
    This paper presents two different formulations for introducing point-masses into a dynamic problem using the Generalized Beam Theory (GBT) method. The first one implies placing a point-mass at a beam-node (with or without ...
  • Modelling of pallet rack connections by means of a geometrically nonlinear analysis based on the Generalized Beam theory 

    Bonada Bo, Jordi; López Rull, Ignasi; Bové Tous, Oriol; Casafont Ribera, Miguel (2024-11)
    Article
    Open Access
    This paper presents a formulation to reproduce the main connections of pallet rack structures by means of a Generalized Beam Theory analysis. Different approaches to modelling the upright-to-brace and upright-to-beam ...
  • Global analysis of adjustable pallet rack down-aisle frames using the generalised beam theory 

    Bonada Bo, Jordi; Bové Tous, Oriol; Casafont Ribera, Miguel; López Rull, Ignasi (Multidisciplinary Digital Publishing Institute, 2024-06-25)
    Article
    Open Access
    A global analysis of a rack frame conducted using the Generalised Beam Theory (GBT) is presented. This study specifically focuses on a down-aisle frame, showing the particular characteristics of this type of structure, ...
  • A chimera method for thermal part-scale metal additive manufacturing simulation 

    Slimani, Mehdi; Cervera Ruiz, Miguel; Chiumenti, Michele (Elsevier, 2024-11)
    Article
    Restricted access - publisher's policy
    This paper presents a Chimera approach for the thermal problems in welding and metallic Additive Manufacturing (AM). In particular, a moving mesh is attached to the moving heat source while a fixed background mesh covers ...
