The maximum tangential strain energy density (MTSED) criterion was modified by taking the influences of stress intensity factors and T-stress into consideration for combined mode I-III brittle fracture. Furthermore, the Poisson's ratio and T-stress influencing the fracture characteristics of cracked components were discussed by using the extended MTSED criterion. Moreover, the predicted values of this extended MTSED criterion and some testing results were comparatively analysed. The results indicate that the Poisson's ratio and T-stress have no impact on the out-of-plane initiation angle; however, their effects on fracture resistance ratios are significant especially for pure mode III. A positive T-stress increases the fracture resistance ratio, and it is opposite for a negative T-stress. The predicted values calculated by the extended MTSED criterion agree very well with the testing data obtained with edge-notched disc bend samples especially for pure mode III case.

“…For example, He et al 36 measured the values of K IIc for asphalt mixture by four specimens, namely, CCBD, SCB, asymmetric SCB (ASCB), and AENDB, in the range of 0.56 to 1.14 MPaÁm 0.5 . In these experiments, researchers [32][33][34][35][36][37] have attributed the large differences in the values of K IIc measured for different specimens to the presence of T-stresses of different magnitudes and signs in specimens with different geometries and configurations.…”

“…Aliha 34 and his colleagues also investigated the effect of geometry and size effects on the fracture trajectory of limestone cracked specimens under I/II mixed mode loading by central cracked Brazilian disc (CCBD) and SCB specimens. The asphalt mixture has also been adopted by some researchers 35–37 to carry out experimental studies on I/II mixed mode crack. For example, He et al 36 measured the values of K IIc for asphalt mixture by four specimens, namely, CCBD, SCB, asymmetric SCB (ASCB), and AENDB, in the range of 0.56 to 1.14 MPa·m 0.5 .…”

When the elastic‐brittle cracked body is subjected to compressive‐shear loading, not only does the phenomenon of wing crack initiation and propagation occur, but there is also a notable incidence of secondary crack initiation and propagation due to shear stress. Moreover, the shear fracture toughness (KIIc) predicted by the fracture criterion in the framework of classical fracture mechanics is usually smaller than the tensile fracture toughness (KIc), which is inconsistent with the actual observations. Therefore, this research firstly establishes a mechanical model of an elastic‐brittle cracked body under biaxial compression considering three kinds of crack parameters and materials' mechanical properties. Then, the stress field characteristics at the crack tip are analyzed. Next, a compression‐shear mixed fracture criterion is proposed. Finally, the effects of the lateral pressure coefficient (λ), critical plastic zone size (rc), friction coefficient (f), and deformation parameters of the crack surface on the failure modes at the crack tip are investigated.

“…Discrete results of fracture toughness values are usually analyzed using probabilistic failure principles, and the Weibull model, a typical probability function for brittle failure [19], is a probability distribution function proposed by the Swedish scientist W. Weibull as an effective model for the discrete analysis of fracture toughness data for asphalt concrete [20]. Scholars have investigated the applicability of Weibull distribution curves in predicting the fracture toughness of different materials such as asphalt concrete [21,22], rock [23,24], polymers [25,26], composites [27], ceramics [28], and carbon fibers [29]. The results show that the Weibull statistical method can provide a better engineering evaluation of the cracking resistance of the above materials.…”

The cracking problem of asphalt concrete panels is a crucial consideration in the design of hydraulic asphalt concrete seepage control bodies. Panels experiencing uneven rises or falls of water levels during impoundment may exhibit loading rate effects. Investigating the fracture toughness value of asphalt concrete under varying loading rates is essential. This study employs a statistical method to calculate the fracture index KIC, using the semi-circular bending test (SCB) to examine the effect of loading rates on the Type I fracture mode of hydraulic asphalt concrete. The data are analyzed using the two-parameter Weibull distribution curve, offering insights into the minimum number of KIC test specimens. The results indicate an increase in KIC with loading rate, with greater data dispersion at faster rates. The Weibull distribution curve successfully fits the fracture behavior under different loading rates, providing valuable predictions. This study estimates the minimum number of SCB test specimens to be nine, based on a confidence level of 0.95 and a relative deviation not exceeding 5%.
