A disk-shaped domain integral method for the computation of stress intensity factors using tetrahedral meshes (2015, methodology): “Numerical and experimental results have recently demonstrated that higher order terms of the crack tip asymptotic field, in particular T-stress, can also influence the stress distribution near the crack tip, and consequently the onset of fracture growth (Smith et al., 2001; Ayatollahi et al., 2006; ”
An improved semi-circular bend specimen for investigating mixed mode brittle fracture (2011, unknown): “This figure is in the range of 1–2 MPa ffiffiffiffiffi m p reported in previous papers for fracture toughness of PMMA [9,18,30].”
Application of Cracked Triangular Specimen Subjected to Three-Point Bending for Investigating Fracture Behavior of Rock Materials (2013, background): “…et al. 2008), and the edge cracked semicircular bend specimen (Chong and Kuruppu 1984; Chong et al. 1987; Singh and Sun 1990; Krishnan et al. 1998; Lim et al. 1994; Ayatollahi et al. 2006; Aliha et al. 2010, 2012) are some of the frequently used specimens for mixed-mode fracture tests on rocks.”
