Analysis of a new specimen for mixed mode fracture tests on brittle materials (2009, methodology): “This concept can be studied by using the formulations given in [28] for the modified criterion in mixed mode loading.”
Measurement of mode I and mode II rock dynamic fracture toughness with cracked straight through flattened Brazilian disc impacted by split Hopkinson pressure bar (2011, methodology): “GMTS criterion is taken to predict the crack initiation angle, crack extension direction is perpendicular to the direction of maximum tensile stress [13].”
Application of Cracked Triangular Specimen Subjected to Three-Point Bending for Investigating Fracture Behavior of Rock Materials (2013, methodology): “It is now well established that the stress intensity factors KI and KII as well as the T-stress are three important characteristic parameters for mixed-mode brittle fracture problems (Williams and Ewing 1972; Smith et al. 2001; Ayatollahi and Aliha 2008a, b).”
An improved semi-circular bend specimen for investigating mixed mode brittle fracture (2011, positive): “For such materials, one would expect to obtain higher values of mixed mode fracture toughness from the ASCB experiments; because the GMTS suggests that the effect of T-stress in mixed mode brittle fracture is more pronounced for materials having larger values of rc [34].”
A disk-shaped domain integral method for the computation of stress intensity factors using tetrahedral meshes (2015, positive): “Numerical and experimental results have recently demonstrated that higher order terms of the crack tip asymptotic field, in particular T-stress, can also significantly influence the stress distribution near the crack tip, and consequently the onset of fracture growth (Smith et al., 2001; Ayatollahi ”
On determination of mode II fracture toughness using semi-circular bend specimen (2006, positive): “Recent studies by Ayatollahi and his co-workers (Smith et al., 2001; Ayatollahi et al., 2002; Ayatollahi and Aliha, 2004) have revealed that in addition to the stress intensity factors KI and KII, the non-singular stress term (often known as T-stress) has significant effects on brittle fracture in…”
T-stress in orthotropic functionally graded materials: Lekhnitskii and Stroh formalisms (2004, background): “Smith et al. (2001) revisited earlier experimental results for brittle fracture of PMMA, and re-examined the role of the T-stress in brittle materials.”
