• 3D numerical study of the transient behaviour on plasticity induced crack closure 

      Camas, Daniel; Antunes, Fernando; Lopez-Crespo, Pablo; Gonzalez-Herrera, Antonio (2019-07-05)
      The numerical analysis of the plasticity induced crack closure requires the development of the plastic wake. Transient behaviour is observed when the crack starts to grow. The plastic wake length has an influence on the ...
    • Correlation between the pivot node concept and fatigue crack closure 

      Camas, Daniel; Gozalez-Herrera, Antonio; García-Manrique-Ocaña, José Manuel (2018-10-05)
      The study of fatigue crack growth has been commonly done by means of bi-dimensional models and assuming a homogeneous behaviour through the thickness. According to the specimen thickness, a state of plane stress or plane ...
    • 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 ...
