Studying on the fatigue behavior of Al- Al2O3 metal matrix nano composites processed through powder metallurgy

Excellent mechanical properties and fatigue performance of Al/Al2O3 metal-based nanocomposites caused to introduce this material as a good candidate for various applications. In this regard, the preparation and characterization of this composite can be considered as a hot issue for research. The study was carried out in several steps including: (i) preparation of Al/Al2O3 metal-based nanocompos...

Fracture Mechanics and Corrosion Fatigue

The development and current state-of-the-art in fracture mechanics in relation to studies of environment-enhanced fatigue-crack growth (corrosion fatigue) and fatigue-crack growth per se are reviewed. Patterns of response of materials to different loading and environmental conditions are considered in terms of the probable mechanisms for environmental embrittlement. The usefulness of the fractu...

Fatigue fracture of hydrogels

Rapid advances are taking place to develop hydrogels of high stretchability and toughness, but fatigue fracture has not been studied for any hydrogels. This negligence hinders the development of hydrogels and their applications. Herewe initiate a study of fatigue fracture of hydrogels.We choose polyacrylamide hydrogel as a model material. To place fatigue fracture in context, we apply monotonic...

Stress Concentrations , Fatigue , Fracture

The fundamental topic in this document is the development of cracks in steel. For structures subjected to cyclic loads, such cracks can develop over time and ultimately reach the size at which some dramatic failure occur. While this problem is rare in structures made of “mild steel,” the use of “high tensile” steel changes that situation. It is straightforward to double the strength of mild ste...

Fracture and Fatigue-Crack Growth Behavior in Mo-12Si-8.5B Intermetallics at Ambient and Elevated Temperatures

perhaps the most progress has been made with alloys based on nickel and especially titanium aluminides. These alloys can Boron-containing molybdenum silicides have received some exhibit significant room temperature ductility, at least compared interest of late due to their superior low-temperature "pest" to other intermetallics, but have the major disadvantage that their resistance and comparab...
