Corrosion damage in civil, aeronautical, and mechanical systems poses significant risks to users and occupants while simultaneously burdening owners with costly repairs and maintenance. Although many different sensing technologies are available to monitor corrosion processes, many cannot be easily implemented in field environments due to requiring expensive data acquisition systems and their de...

Although bulk silicon is not known to exhibit susceptibility to cyclic fatigue, micron-scale structures made from silicon films are known to be vulnerable to degradation by fatigue in ambient air environments, a phenomenon that has been recently modeled in terms of a mechanism of sequential oxidation and stress-corrosion cracking of the native oxide layer. To date, most stress-life (S=N ) fatig...

Low temperature carburizing (LTC) treatment improves surface hardness and wear resistance of the austenitic stainless steels without reducing their corrosion resistance. Surface hardness over 1000 Vickers and compressive residual stresses whose modulus exceeds 1500 MPa are usually achieved in the carburized layer, thanks to the formation of the so-called “S-phase”, a carbonsupersaturated austen...

Cables play an important role in cable-stayed systems, but are vulnerable to corrosion and fatigue damage. There is a dearth of studies on the fatigue damage evolution of corroded cable. In the present study, the acoustic emission (AE) technology is adopted to monitor the fatigue damage evolution process. First, the relationship between stress and strain is determined through a tensile test for...

Eddy current testing is an effective way of detecting fatigue cracks and corrosion in conductive materials. The cost of using the technology is low, and the devices can monitor subsurface defects and defects under insulating coatings without touching the surface of the specimen. Although this technique is applicable for many tasks, the aircraft and nuclear power industries are the primary users...

Internal fixations provide fast healing but their failure remains problematic to patients. Here, we report an experimental study in failure of three typical cases of metals: a bent intramedullary stainless steel nail, a broken exterior pure Ti plate, and a broken intramedullary stainless steel nail. Characterization of the bent nail indicates that those metals are vulnerable to corrosion with t...

This paper presents an experimental study on the monotonic and fatigue behavior of a link slab designed for a durable concrete bridge deck system. The requirements on the link slab in terms of material properties, dimensions, and reinforcement detailing are considered. Special focus is placed on the deflection capacity of the link slab and its fatigue performance. This paper discusses the choic...
