      In this work a limit analysis for 3D structures software package is presented. The goal is to obtain for a certain structure the load factor λ that applied to the external loads induces collapse to the structure. The ...

      Muñoz, José J.; Huerta, Antonio; Bonet Carbonell, Javier; Peraire Guitart, Jaume (2009-04-03T10:56:47Z)
      Text en actes de congrés
      Accés obert
      By writing the limit state analysis as an optimisation problem, and after resorting to suitable discretisations of the stress and velocity field, we compute strict bounds of the load factor. The optimisation problem is ...
    • Updated Lagrangian formulation for corrected smooth particle hydrodynamics 

      Huerta, Antonio; Vidal Seguí, Yolanda; Bonet Carbonell, Javier (2006-12)
      Article
      Accés obert
      Smooth Particle Hydrodynamics (SPH) are, in general, more robust than finite elements for large distortion problems. Nevertheless, updating the reference configuration may be necessary in some problems involving extremely ...
