At the same time, the rock-breaking behavior and mechanism of the worn PDC cutter are not clear. Therefore, in order to study the effect of drill bit wear on rock-breaking performance and explore the rock-breaking performance of worn PDC cutters, in this paper, we take the red sandstones as the experimental objects, and use five PDC cutters with different wear lengths obtained by machining. The influence of the worn PDC cutter on the rock-breaking process is studied from the aspects of the cutting force, the mechanical specific energy (MSE), the coefficient of friction, and the cutting groove. The results show that the axial force and tangential force increase and decrease synchronously with the increase of cutting depth, but with local differences, and the wear length significantly influences the response mode of cutting force by the change of cutting depth. In addition, wear blunts the cutting edge leading to homogenization of the shear deformation, which results in the MSE first decreasing and then increasing as the degree of wear increases. At the same time, the rate of stress growth is lower than area growth rate, resulting in a decrease in normalized aggressiveness with increasing depth of cutting. The contact area of the worn PDC cutter with the rock increases, resulting in a decrease in normalized aggressiveness with increasing wear length. Finally, wear leads to a greater squeezing and grinding action of the PDC cutter on the rock, and the cutting grooves of the worn PDC cutter are thicker and wider than the sharp PDC cutter. In this study, the wear evaluation model constructed reveals the stage threshold effect of PDC cutter wear, confirms that the balance between frictional energy consumption and cutting efficiency are broken when the wear length is 1.5 mm, which provides a theoretical basis for the prediction of PDC drill bit wear and the optimization of its life.</div></div>","PeriodicalId":11677,"journal":{"name":"Engineering Failure Analysis","volume":"182 ","pages":"Article 110094"},"PeriodicalIF":5.7,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145266201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specimens were cured at 40 °C for 3, 7, and 14 days to assess the effect of curing duration on CMA’s cracking behavior. Mixture properties were first evaluated using Indirect Tensile Strength (ITS) and Tensile Strength Ratio (TSR), followed by the Indirect Tensile Asphalt Cracking Test (IDEAL-CT) to quantify cracking resistance through the cracking tolerance index (CT_index) and cracking brittleness index (CB_index). Furthermore, grey relational analysis (GRA) was used to evaluate the relative influence of filler type, curing duration, and conditioning on the cracking behaviour of the mix. ITS results showed strength gains of 17.6 % and 58.6 % at 7 and 14 days of curing, respectively, compared to 3 days of curing, while full filler replacement exhibited reduced moisture resistance. IDEAL-CT indicated increases in fracture energy (G_f) by 16.3 % and 51.6 %, and strain tolerance index (l₇₅) by 15.5 % and 9.1 %, over the curing periods of 3–7 and 3–14 days, respectively. CT_index ranged from 500 to 1000 for dry-conditioned specimens and 1000–2000 for wet-conditioned samples, while CB_index decreased from 400 to 700 under dry conditions to 100–400 for wet mixes. GRA confirmed curing duration as the most influential factor, while filler type had minimal effect (Δ ≤ 0.086). Overall, extending the curing time enhanced the cracking resistance, with moderate filler replacement providing the optimal balance between strength and durability.</div></div>","PeriodicalId":11677,"journal":{"name":"Engineering Failure Analysis","volume":"182 ","pages":"Article 110129"},"PeriodicalIF":5.7,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145095964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This can potentially lead to support failure, making it crucial to clarify the underlying mechanisms for safe tunneling. This study focuses on the DJ Tunnel located in the Badong Formation of yellow mudstone in Wuxi County, Chongqing. This research conducted uniaxial and triaxial compression tests, as well as uniaxial multi-stage loading creep tests under both natural and saturated conditions, to quantify the water-induced weakening of mechanical parameters and creep characteristics. Building on the viscoelasto-plastic behavior of the rock and the laws of damage evolution, a damage creep constitutive model was developed and validated against laboratory data. Compared to the Burgers-Mohr model, the new model more comprehensively captures the complete three-stage creep process (decelerating, steady-state, and accelerating), accurately reflecting the onset and progression of accelerated creep, and aligning more closely with the experimental curves. Subsequently, a tunnel-scale FLAC3D model was established to compare the spatiotemporal evolution of surrounding rock deformation and the stress distribution of support structures under natural versus saturated conditions. The results indicate that peak strength is negatively correlated with water content and positively correlated with confining pressure, suggesting that increased confinement can mitigate the effects of water-induced softening. Saturated mudstone demonstrated more sensitive creep parameters and a faster deformation response. Parametric analyses reveal that increasing the thickness of the initial shotcrete, extending the anchorage length of prestressed bolts, and optimizing the timing of the secondary lining casting can significantly reduce surrounding rock deformation. These findings provide a theoretical foundation and essential technical parameters for the stability control of tunnels in water-sensitive strata.</div></div>","PeriodicalId":11677,"journal":{"name":"Engineering Failure Analysis","volume":"182 ","pages":"Article 110121"},"PeriodicalIF":5.7,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145095976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Motivated by this need, this study proposes a comprehensive framework to simulate the overturning collapse process based on explicit nonlinear dynamic finite element analysis. Incremental dynamic analysis, combined with a bisection search algorithm, is employed to determine the load-carrying capacity. A case study is conducted to systematically compare the proposed method with existing approaches. The results reveal that bridge overturning is primarily driven by the coupled effects of torsion and sliding under vehicle loads. The overturning process of the girder bridge can be divided into three stages: the small rotation stage, the torsion-sliding coupling stage, and the failure stage. The alignment between the accident scenario and the simulation results demonstrates that the proposed method can accurately reproduce the overturning process and capture the damage of key components. Moreover, the study reveals that traditional assessment approaches may yield inaccurate estimations of the critical failure load, primarily due to their neglect of girder sliding behavior and dynamic effect of vehicle movement during the overturning process.</div></div>","PeriodicalId":11677,"journal":{"name":"Engineering Failure Analysis","volume":"182 ","pages":"Article 110123"},"PeriodicalIF":5.7,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145109124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
