    • A blended shifted-fracture/phase-field framework for sharp/diffuse crack modeling 

      Li, Kangan; Rodríguez Ferran, Antonio; Scovazzi, Guglielmo (2023-02-28)
      Article
      Open Access
      The shifted fracture method (SFM) is an embedded method that enables sharp crack representations while using mesh-fitted data structures. In the SFM, the true crack is embedded in the computational grid, but the crack ...
    • A kinematically stabilized linear tetrahedral finite element for compressible and nearly incompressible finite elasticity 

      Scovazzi, Guglielmo; Zorrilla Martínez, Rubén; Rossi, Riccardo (2023-07)

      We propose a stabilized linear tetrahedral finite element method for static, finite elasticity problems involving compressible and nearly incompressible materials. Our approach relies on a mixed formulation, in which the ...
    • A shifted boundary method based on extension operators 

      Zorrilla Martínez, Rubén; Rossi, Riccardo; Scovazzi, Guglielmo; Canuto, Claudio; Rodríguez Ferran, Antonio (Elsevier, 2024-03)
      Article
      Open Access
      We consider formulations of the Shifted Boundary Method based on extrapolation operators other than the Taylor expansion. In the specific case of the Poisson equation, we prove that this approach is stable, provided some ...
    • The shifted fracture method 

      Li, Kanging; Atallah, Nabil M.; Rodríguez Ferran, Antonio; Valiveti, Dakshina M.; Scovazzi, Guglielmo (2021-11-30)
      Article
      Open Access
      We propose a new framework for fracture mechanics, based on the idea of an approximate fracture geometry representation combined with approximate interface conditions. Our approach evolves from the shifted interface method, ...
