“…Thus, the simulation results near the free surface of the specimen can be ignored. In the study of the effects of thickness and Poisson's ratio by Aliha and Saghafi [30], the SIFs and T-stress in the middle position of the crack were taken as the simulation result, and a good research achievement was seen. Our study also used that method.…”

“…The effects of thickness and Poisson's ratio on 3D mixed-mode I/II fractures were studied by using edge-cracked semi-circular bend (SCB) specimens [27]. Further, mixedmode I/II fracture experiments using SCB specimens with different materials, such as hotmix asphalt (HMA) [8], marble [28], limestone [19], sandstone [29] and acrylonitrile butadiene styrene [30], have been tested and analyzed. The results showed that SCB specimens were suitable to study the fracture of HMA at a low temperature [8].…”

“…The prediction of the crack initiation angle was affected by SIFs and the non-singular term (T-stress), and the value and sign of T-stress in the mixed-mode I/II fracture of SCB specimens played important roles [19]. The internal structure of the material also affected the fracture toughness and fracture mode [30]. An edge-cracked triangular (ECT) specimen and an edge-cracked short-bend beam specimen of mixed-mode I/II fracture were also studied [31,32].…”

“…These criteria only considered the singular term of the stress field at the crack tip and ignored the non-singular term (T-stress). However, a large number of experiments have proven that the fracture criterion considering the non-singular term can predict the experimental results more effectively [16][17][18][19][20]26,28,30,31,[37][38][39][40]. It was found that the generalized maximum tangential stress (GMTS) or generalized maximum tangential strain (GMTSN) criteria, both considering T-stress, can better predict the central cracked disc experimental results of mixed-mode I/II fractures compared with the MTS criterion [16][17][18][19][20].…”

The GMTS criterion was also used to predict and verify the experimental results of three-point bending specimens in mixed-mode I/II fracture studies, whether SCB or ETC specimens [26,28,30,31]. The mixed-mode I/III fracture experimental results for various materials such as marble [37], asphalt concrete [39] and graphite [40] using ENBD specimens were in good agreement with the theoretical predicted value of the MTSED criterion without considering T-stress.…”

The crack-propagation form may appear as an arbitrary mixed-mode fracture in an engineering structure due to an irregular internal crack. It is of great significance to research the mixed-mode fracture of materials with cracks. The coupling effect of multiple variables (crack height ratio, horizontal deflection angle and vertical deflection angle) on fracture parameters such as the stress intensity factors and the T-stress are the key points in this paper. A three-point bending specimen with an inclined crack was proposed and used to conduct mixed-mode fracture research. The fracture parameters were obtained by finite element analysis, and the computed results showed that the pure mode I fracture and mixed-mode fractures (mode I/II, mode I/III and mode I/II/III) can be realized by changing the deflection angles of the crack. The pure mode I and the mixed-mode fracture toughness of sandstone were obtained by a series of mixed-mode fracture experiments. The experimental results were analyzed with the generalized maximum tangential strain energy density factor criterion considering T-stress. The results showed that the non-singular term T-stress in the fracture parameters cannot be ignored in any mixed-mode fracture research, and the generalized maximum tangential strain energy density factor criterion considering T-stress can better predict the mixed-mode fracture toughness than other criteria.

The increasing application of additive manufacturing (AM) technology across various sectors has sparked significant interest in characterizing 3D‐printed components. An essential aspect of achieving fracture‐resistant designs is gaining a comprehensive understanding of the fracture behavior exhibited by these components. While most studies have focused on linear‐elastic fracture mechanics (LEFM), there is a lack of comprehensive studies on the post‐yield fracture behavior (PYFM) of 3D‐printed components. As a result, this study aims to fill this gap by investigating the impact of raster angle, a critical parameter influencing fracture properties and often leading to premature failures, on the fracture properties of fused deposition modeling (FDM) 3D printed acrylonitrile butadiene styrene (ABS) using essential work of fracture (EWF). Outcomes showed that by changing lay‐ups from [90]5 to [0]5, the value of we or elastic work increased by nearly 306%. Further, the maximum and minimum values of the plastic work (βwp) were for [45/−45/45/−45/45] and [90]5 lay‐ups, in order. By changing lay‐ups from [90]5 to [45/−45/45/−45/45], the value of βwp increased by approximately 216%. In addition, the fractured surfaces of tested samples are also analyzed to provide insights into the dominant failure mechanisms for different raster angles.
