• 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 ...
    • Experimental and analytical study of cracks under biaxial fatigue 

      Mokhtarishirazbad, M; Lopez-Crespo, Pablo; Moreno, B; Camas, Daniel; Lopez-Moreno, A; [et al.] (GIF, 2016)
      Most mechanical components experience multi-axial cyclic loading conditions during service. Experimental analysis of fatigue cracks under such conditions is not easy and most works tend to focus more on the simpler but ...
    • Some experimental observations of crack-tip mechanics with displacement data 

      Lopez-Crespo, Pablo; Mokhtari, M; Moreno, B; Zanganeh, M (GIF, 2015-05-01)
      In the past two decades, crack-tip mechanics has been increasingly studied with full-field techniques. Within these techniques, Digital Image Correlation (DIC) has been most widely used due to its many advantages, to ...
    • Study of the stress intensity factors in the bulk of the material with synchrotron diffraction 

      Lopez-Crespo, Pablo; Vazquez-Peralta, J; Simpson, C; Moreno, B; Buslaps, T; [et al.] (Engineering Integrity Society, 2017)
      In this work we present the results of a hybrid experimental and analytical approach for estimating the stress intensity factor. It uses the elastic strains within the bulk obtained by synchrotron X-ray diffraction data. ...
