• A numerical analysis of the relation between CTOD and fatigue crack growth 

      Camas, Daniel; Antunes, F.V.; Rodrigues, S.M. (2016-03-30)
      El cálculo de la vida a fatiga durante la etapa de propagación de la grieta se suele realizar relacionando da/dN con ΔK. Sin embargo, la influencia que en estos análisis tiene el parámetro ΔK debe recaer en algún otro ...
    • Influencia del tamaño mínimo de elemento en el análisis tridimensional por elementos finitos del cierre de grieta inducido por plasticidad 

      Camas, Daniel; Lopez-Crespo, Pablo; Moreno, B; Zapatero, J.; González-Herrera, Antonio (2014-04-10)
      Debido al incremento de la capacidad computacional disponible hoy en día, en los últimos años se ha extendido el uso de modelos tridimensionales para el análisis del cierre de grieta en fatiga empleando el método de los ...
    • 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 ...
    • Through thickness evolution of crack tip plasticity 

      Camas, Daniel; Lopez-Crespo, Pablo; Antunes, F. V.; Yates, J. R. (2017-07-19)
      Experimental methods to measure fracture mechanics parameters tend to provide information from or about the surface of cracked components. However, information about the interior of the component is key to understanding ...
