    • A study on finite elements for capturing strong discontinuities 

      Oliver Olivella, Xavier; Huespe, Alfredo Edmundo; Samaniego Alvarado, Esteban (John Wiley & sons, 2003-04)
      Article
      Open Access
      The work focuses on the presently existing families of finite elements with embedded discontinuities and explores the possibilities of obtaining symmetric statically consistent finite elements that alleviate the stress-locking ...
    • Contributions to the continuum modelling of strong discontinuities in two-dimensional solids 

      Samaniego Alvarado, Esteban (Universitat Politècnica de Catalunya, 2003-03-28)
      Doctoral thesis
      Open Access
      El estudio de la mecánica computacional de fallo ha ganado creciente popularidad en los últimos años. Modelizar el comportamiento poscrítico de estructuras puede alcanzar un grado elevado de complejidad, debido a la ...
    • On the strong discontinuity approach in finite deformation settings 

      Oliver Olivella, Xavier; Huespe, Alfredo Edmundo; Gómez Pulido, M. Dolores; Samaniego Alvarado, Esteban (John Wiley & sons, 2003-02)
      Article
      Open Access
      Taking the strong discontinuity approach as a framework for modelling displacement discontinuities and strain localization phenomena, this work extends previous results in infinitesimal strain settings to finite deformation ...
