• Key aspects in 3D fatigue crack closure numerical modelling 

      Camas, Daniel; Gonzalez-Herrera, Antonio; García-Manrique-Ocaña, José Manuel (2018-09-14)
      Since long time, fatigue crack closure has been studied by means of finite element models. Initially by bi-dimensional models and recently, due to the higher computational capabilities, the use of three-dimensional models ...
    • Numerical analysis of the influence of the last cycle scheme on plasticity induced crack closure 

      Camas, Daniel; Antunes, Fernando; Moreno-Morales, Maria Belen; Gonzalez-Herrera, Antonio (2019-09-24)
      Plasticity induced crack closure is considered the main mechanism related to the premature contact of the crack flanks when a crack grows under cyclic loadings. This phenomenon has been studied numerically since the early ...
    • Numerical analysis of the pivot node in fracture problems 

      Camas, Daniel; Gonzalez-Herrera, Antonio; García-Manrique-Ocaña, José Manuel; Lima-Rodríguez, Antonia (2018-09-14)
      Recent studies have allowed us to identify a narrow region of the thickness of the crack front in fracture problems that presents interesting characteristics for the numerical-experimental correlation. Taking the ...
