    • A robust and scalable unfitted adaptive finite element framework for nonlinear solid mechanics 

      Badia, Santiago; Caicedo Silva, Manuel Alejandro; Martín, Alberto F.; Principe, Ricardo Javier (2021-12)
      Article
      Accés obert
      In this work, we bridge standard Adaptive Mesh Refinement and coarsening (AMR) on scalable octree background meshes and robust unfitted Finite Element (FE) formulations for the automatic and efficient solution of large-scale ...

    • Arbitrary Lagrangian-Eulerian (ALE) formulation for hyperelastoplasticity 

      Rodríguez Ferran, Antonio; Pérez Foguet, Agustí; Huerta, Antonio (Wiley and Sons, 2002-02)
      Article
      Accés obert
      The arbitrary Lagrangian-Eulerian (ALE) description in non-linear solid mechanics is nowadays standard for hypoelastic-plastic models. An extension to hyperelastic-plastic models is presented here. A fractional-step method ...

    • New ALE applications in non-linear fast-transient solid dynamics 

      Huerta, Antonio; Casadei, F. (1994-08)
      Article
      Accés obert
      The arbitrary Lagrangian—Eulerian (ALE) formulation, which is already well established in the hydrodynamics and fluid-structure interaction fields, is extended to materials with memory, namely, non- linear path-dependent ...
