In practical high-temperature service environments, the TiAl alloys frequently experience synergistic interactions among various damage mechanisms, including creep, fatigue, and oxidation, which can severely impair their mechanical integrity and reduce component lifetime. This review presents a critical overview of the predominant high-temperature damage modes in TiAl alloys, focusing on the mechanisms and research advancements related to creep damage, fatigue damage, and oxidation damage. This paper further explores coupled damage mechanisms such as thermomechanical fatigue, creep-fatigue interaction, creep-oxidation interaction and environmental hydrogen embrittlement. Additionally, it discusses strategies for enhancing damage resistance through the design of alloying elements and the application of coating technologies in detail. Currently, understanding of the coupled damage mechanisms in high-temperature TiAl alloys remains incomplete, and further research is hindered by the complexity of multi-field coupling and the limitations of the intrinsic properties of material. Future efforts should concentrate on achieving a more profound understanding of the microscopic mechanisms underlying coupled damage, as well as on the development of more effective alloying and coating technologies. These advancements are essential to meet the increasing performance demands for high-temperature TiAl alloys in aerospace applications.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"29 ","pages":"Article 109754"},"PeriodicalIF":7.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147394386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on 308 Scopus publications from 2021 to 2025, it combines bibliometric mapping with an in‑depth analysis of 20 key studies to track research growth, themes, and international collaborations. Advanced AI models—convolutional neural networks, long‑short‑term memory networks, temporal convolutional networks, and attention‑based hybrids—enhance real‑time structural health monitoring, damage detection, and seismic response prediction. Multimodal data fusion and transfer learning further improve predictive accuracy and support proactive maintenance. Overall, AI‑driven approaches complement inspections and finite‑element models by providing rapid, data‑driven decision support for the design, monitoring, and management of bridges under earthquakes, floods, fire, and strong winds. The review identifies three priorities: embedding AI within digital twins and decision‑support systems for network‑level bridge management; extending applications beyond seismic hazards to a unified multi‑hazard resilience framework; and explicitly addressing data quality, uncertainty, and explainability so AI tools can be trusted in safety‑critical settings. An AI‑integrated bridge digital‑twin framework is proposed to link multimodal sensing, hybrid/PINN‑enabled prediction, and risk‑informed outputs for real‑time monitoring, early warning, and maintenance planning.

Grid-reinforced ECC panels combine the stiffness and flexural strength of grids with ECC’s strain-hardening behavior. Despite these advantages, the flexural performance of these panels can be compromised by premature debonding, which may occur before the design loads are reached. This study explores the grooving method (GM) in the form of externally-bonded reinforcement on grooves (EBROG) to reduce such failures. Therefore, an optimal transverse groove arrangement for installing grid-reinforced ECC panels was adopted as a novel approach. First, direct tensile and four-point bending tests were conducted to study the flexural behavior, strain capacity, and tensile strength of both unreinforced and grid-reinforced ECC panels. Then, five reinforced concrete (RC) beams were constructed and tested under four-point bending to investigate the influence of ECC panels utilized for flexural retrofitting on the maximum load, failure mode, ductility, and energy dissipation. Polypropylene (PP) and polyvinyl alcohol (PVA) fibers were incorporated into the ECC panels, and two types of grids (glass and steel) were used for panel reinforcement. The results showed that the displacement and energy ductility indices of the strengthened beams were enhanced by an average of 79 % and 51 %, respectively, compared to the reference. Notably, beams retrofitted with PVA and PP ECC panels demonstrated average improvements in maximum load capacities of 27 % and 20 %, respectively. Consequently, PP ECC demonstrated performance similar to PVA ECC, suggesting that PP fibers could be a cost-effective alternative while maintaining enhanced flexural performance. The study also validated an analytical method for calculating the nominal moment capacity of the RC beams, demonstrating satisfactory performance.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"29 ","pages":"Article 108502"},"PeriodicalIF":7.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145683952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
