Special Issue Information

Dear Colleagues,

Corrosion fatigue is the most frequently encountered failure mode of materials and structures, and it is related to the electrochemical damage and propagation of cracks caused by fatigue loads and corrosive action. The cracking and fracture that result from corrosion fatigue are a matter of concern regarding long-term services for engineering structures. Fracture mechanics and an environment-enhanced fatigue–crack growth model have been proposed in order to understand the complex failure mechanism, approaches to evaluation employed and control measures used. As metal materials and modern fiber-reinforced materials continue to be utilized, fracture mechanics requires development. It is now imperative to study fracture mechanics due to the increased attention paid to the corrosion fatigue of land-based structures, marine structures, aerospace structures, and engineering structures for sustainable energy generation and storage.

The aim of this Special Issue, entitled “Fracture Mechanics and Corrosion Fatigue”, is to present studies on the fracture and corrosion fatigue of structure; its scope includes, but is not limited to, the following:

(1) Fracture mechanics and environment-enhanced fracture model for metal and modern fiber-reinforced materials.
(2) Corrosion fatigue testing and failure analysis of engineering materials and structures.
(3) Multi-scale and multi-physical simulation of fracture and corrosion fatigue process.
(4) Evaluation and improvement of corrosion fatigue performance.
(5) Corrosion fatigue, hydrogen-assisted fatigue, corrosion-fretting fatigue.

In practical engineering, due to quality inspections of connections between prefabricated components and construction errors, reserved reinforcing bars in the transition layer may be partially insufficient or even completely absent. This defect significantly impacts the structural performance of sleeve connections, particularly under tensile or shear forces. This paper proposes a novel reinforcement method to address the connection issues caused by the absence of reserved reinforcing bars in the transition layer and verifies its feasibility through systematic experiments. To this end, this paper proposed a novel reinforcement method of grouting sleeve connection considering the absence of reserved bars in the transition layer, and 45 specimens with different reinforcement parameters were fabricated and tested under tension. Before verifying the reliability of the novel reinforcement method, nine specimens were fabricated and tested to verify the weldability of grouting sleeves and reinforcing bars. According to the test results, the fully grouted sleeves, including Grade 45 steel and Q345, showed good weldability with the HRB400 steel bars, while the ductile iron grouted sleeve showed poor weldability. When the single-sided welding length was greater than or equal to six times the diameter of the post-retrofitted connecting steel bar (D2), the primary failure mode observed in specimens utilizing the novel reinforcement method was the fracture of the prefabricated steel bar. The novel reinforcement method could be used to repair the defect of the grouting sleeve connection considering the absence of reserved reinforcing bars in the transition layer. When the single-sided welding length was 4D2, with a relative protective layer thickness of 2D2, and using C60 grade reinforcement material, this combination of conditions represented the critical condition to avoid weld failure between the grouting sleeve and the post-retrofitted connecting steel bars. In practical reinforcement projects, it is suggested that the single-sided welding length should be 5D2, the relative protective layer thickness should be 3D2, and the reinforcement material strength should be C60.

This paper presents the experimental results of a study evaluating the mechanical and fatigue performance of welded Fe-Mn-Si SMA. For the experimental study, welded and welded-and-heat-treated Fe-Mn-Si SMA specimens were fabricated, and fatigue tests were performed at various stress amplitudes. In addition, direct tensile tests and recovery stress tests were also performed to evaluate the material properties of Fe-Mn-Si SMAs. The elastic modulus, yield strength, and tensile strength of the welded specimens were reduced by 35.4%, 12.1%, and 8.6%, respectively, compared to the values of the non-welded specimens. On the other hand, the elastic modulus, yield strength, and tensile strength of the welded-and-heat-treated Fe-Mn-Si SMA specimens were increased by 18.6%, 4.9%, and 1.3%, respectively, compared to the values of the welded specimens. Both welded and welded-and-heat-treated Fe-Mn-Si SMAs failed at lower cycles than the conventional Fe-Mn-Si SMAs at the same stress amplitude. High-cycle fatigue failure, characterized by cycles exceeding 104, typically occurs at relatively low stress levels within the elastic region, whereas low-cycle fatigue failure, generally occurring within cycles below 104, involves high stress levels that encompass both elastic and plastic deformation. Regardless of the welding condition, the stress amplitude at which Fe-Mn-Si SMA transitions from high-cycle to low-cycle failure exceeded the yield strength. Full article
