Structural integrity and failure analysis of metallic materials and structures: part II
This Special Issue represents the second part of a set of contributions in the field of structural integrity and failure analysis of metallic materials and structures. In the first part of the Special Issue (Montenegro et al., 2021), a range of research topics related to fatigue analysis of metallic elements (Santos et al., 2020; Viana et al., 2020), fracture mechanics (Smolnicki et al., 2020), steels structures and connections (Jovasevic et al., 2020), optimization algorithms applied to metallic elements (Li et al., 2020), among others (Liu et al., 2020; Mech, 2020; Xie et al., 2020a, b; Cao et al., 2020; Kebir et al., 2020) were covered and published. Several authors have focused on the topic of structural integrity and failure analysis of metallic structural elements. Recently, Pedrosa et al. (2021, 2022) presented a research study to contribute to the scientific knowledge regarding the fatigue behaviour of connections with preloaded injection bolts in the context of a bridge strengthening scenario. Mohabeddine et al. (2021) assessed the fatigue behaviour of the Carbon Fiber Reinforced Polymer (CFRP) retrofitted specimens by means of probabilistic methods where Probabilistic S-N (P-S-N) curves derived using the Castillo & Fernández-Canteli (CFC) model were also proposed. The fatigue performance prediction of riveted connections through experimental investigation has also been addressed (Silva et al., 2021; Correia et al., 2021). Zhu et al. (2021) presented a review study on size effects on metal fatigue under defects. Lesiuk et al. (2021a, b, c, d, e, f) proposed a book on the degradation theory of long-term operated metal materials and structures, where the degradation theory, mechanical properties, microstructure, degradation processes, fatigue and fracture behaviours of metallic materials and components were addressed.
This Part II of the Special Issue on Structural Integrity and Failure Analysis of Metal Materials and Structures, resulted from a number of papers that were subjected to a rigorous peer-review process according to the high scientific standards of the International Journal of Structural Integrity. This special issue is composed of a total of eight papers proposed by engineers and scientists, covering subjects related to the aforementioned topics, such as Weibull statistical data based on Rockwell Hardness (Nam and Son, 2020), failure analysis of high-tension bolts (Nam and Yun, 2020), reliability analysis and safe operation of gas pipelines (Yang et al., 2021; Zhedulov et al., 2021), the relationship between the friction coefficient and interference in rail axles (Liu et al., 2021), efficient steel truss system using CFS sections (Dar et al., 2020), health monitoring and innovative reinforcement of bridges (Zhang et al., 2021a, b).
The guest editors hope this Special Issue provides a remarkable impact on the research related to the structural integrity and failure analysis of metallic materials and structures. The editors also would like to express their gratitude to all authors for their contributions and to all reviewers for their generous work to guarantee the excellence of the accepted papers. Finally, the guest editors would like to express a special thanks to Professor Chris Rodopoulos, and to Professor Shun-Peng Zhu and Doctor José A.F.O. Correia, respectively, Founder Editor and Co-Editors-in-Chief of the International Journal of Structural Integrity, and to Emerald staff for their support during the preparation of this issue. Additionally, this research was funded by the FiberBridge project – fatigue strengthening and assessment of railway metallic bridges using fiber-reinforced polymers [project grant POCI-01-0145-FEDER-030103 composed by FEDER funds provided by COMPETE2020 (POCI) and by national funds (PIDDAC) provided by the Portuguese Science Foundation (FCT/MCTES)]. Support was also provided by CONSTRUCT – Instituto de I&D em Estruturas e Construções that is funded by base funding – UIDB/04708/2020 and programmatic funding – UIDP/04708/2020 provided by national funds through the FCT/MCTES (PIDDAC).
