Influence of paste volume on shrinkage cracking and fracture properties of self-compacting concrete (2007, methodology): “The maps are obtained after selecting the signals with amplitude less than 50 dB, in order to keep only the most energetic micro-cracks associated with concrete fracture [11].”
On the link between fracture toughness, tensile strength, and fracture process zone in anisotropic rocks (2018, methodology): “The FPZ size identified by AE is much larger than the one obtained by microscopy (Zang354 and Wagner, 2000; Otsuka and Date, 2000; Janssen et al., 2001; Backers et al., 2005).”
Localizing gradient damage model with decreasing interactions (2017, background): “Such an evolution of the process zone – for example, observed in concrete experiments [28, 29] and meso-scale simulations [30] – motivates the localizing gradient damage formulation in this section.”
A review of recent developments in parametric based acoustic emission techniques applied to concrete structures (2012, methodology): “Also for specimens with identical maximum aggregate size, the length of the FPZ increased with the increase in specimen size.”
Meso-scale modelling of the size effect on the fracture process zone of concrete (2011, background): “Experimentally, local results have been obtained by acoustic emission measurements (Landis, 1999; Otsuka and Date, 2000; Haidar et al., 2004) and X-ray tomography (Landis et al., 2003).”
Strong discontinuity embedded approach with standard SOS formulation: Element formulation, energy-based crack-tracking strategy, and validations (2015, methodology): “In [21], a finite width of the localization zone, h, was introduced, taking into account the experimentally-observed fracture process zone [22–24].”
A damage model with evolving nonlocal interactions (2011, background): “The variable interaction gives more flexibility to nonlocal models in capturing faithfully the evolving FPZ observed in experiments (Otsuka and Date, 2000).”
Fracture examination in concrete through combined digital image correlation and acoustic emission techniques (2014, methodology): “Both methods are used in literature to calculate the width of FPZ [37,1,2].”
