  • Consistent tangent matrices for substepping schemes 

    Pérez Foguet, Agustí; Rodríguez Ferran, Antonio; Huerta, Antonio (1999-09)
    External research report
    Open Access
    A very simple and general expression of the consistent tangent matrix for substep- ping time-integration schemes is presented. If needed, the derivatives required for the computation of the consistent tangent moduli can ...
  • Efficient and accurate approach for powder compaction problems 

    Pérez Foguet, Agustí; Rodríguez Ferran, Antonio; Huerta, Antonio (2003-02)
    Article
    Open Access
    In this paper, a new approach for powder cold compaction simulations is presented. A density-dependent plastic model within the framework of finite strain multiplicative hyperelastoplasticity is used to describe the highly ...
