• 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 ...
    • 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 ...
