“…Yoshihara (2010a) mentioned that crack propagation is unstable when the a/W ratio is less than 0.3, while it is stable when the ratio is higher than 0.4. In line with the findings of this study, Yoshihara and Mizuno (2014) also confirmed that the a/W ratio should be in the range of 0.5 and 0.7 when determining the critical stress intensity factor value. 4 shows the mean comparisons of fracture properties including initial slope, specific fracture energy, and brittleness number for each a/W ratio.…”

“…Mode I SENB tests were performed on an INSTRON 5566 (Instron, Norwood, MA, USA) universal testing machine. The load P was applied at a crosshead with a speed of 0.5 mm/min (Yoshihara and Mizuno 2014). The load-deformation curves of all tested specimens were loaded until a noticeably propagated crack appeared and were then recorded.…”

“…Therefore, it is necessary to have a good understanding of the fracture properties of PB, which is widely used for construction and furniture manufacturing. The fracture behavior of the wood-based composite can be evaluated using a variety of specimen configurations subjected to tensile, shear, or bending loads, i.e., single-edgenotched bending (SENB) (Yoshihara 2010a;Yoshihara and Mizuno 2014;Marsavina et al 2018;Huang and Wang 2022), single-edge-notched tension (SENT) (Yoshihara 2010b), compact tension (CT) (Yoshihara and Usuki 2011), and double cantilever beam (DCB) (Rathke et al 2012a;Veigel et al 2012).…”

“…The fracture properties of MDF and PB were also investigated under pure modes I and II and also under the mixed mode loading conditions (Torabi et al 2021). Yoshihara and Mizuno (2014) investigated the effects of crack length on the mode I critical stress intensity factor of medium-density fiberboard (MDF) using the SENB test. The results show that the critical stress intensity factor can be obtained effectively under the crack length/specimen width (a/W) ratio ranging from 0.5 to 0.7.…”

The effect of crack length on the fracture behavior of particleboard was investigated using the single-edge-notched bending (SENB) test method under mode I loading. The initial slope (kinit), critical stress intensity factor (KIC), specific fracture energy (Gf), and brittleness number were calculated for five different crack length/specimen width (a/W) ratios varying from 0.1 to 0.9 at intervals of 0.2. The results show that the fracture properties were significantly higher for specimens with an a/W ratio of 0.1 than for the others. However, for the critical stress intensity factor and specific fracture energy, there were no significant differences among the a/W ratios of 0.3, 0.5, and 0.7 where the crack tip was placed in the core layer of the particleboard. In general, as the a/W ratio decreased, the stiffness of the material increased, and the specimens with an a/W ratio of 0.1 showed brittle behavior. However, there was no statistically significant difference between a/W ratios of 0.5 and 0.7.

“…SAFIH [7] studied numerically the harmfulness of semi-elliptical circumferential cracks and in an axisymmetric cylindrical shell with a thickness transition. H. Yoshihara [8] presented the critical stress intensity factor on SENT specimen. HADDAD [9] use the stress distribution at the head of a short crack emanating from a notch, to establish the boundary conditions between the stress concentration factor theory of a blunt cut and that an acute notch.…”
