Review on Concepts of Fracture Control and Damage Tolerance Analysis in advanced composite materials

Shubhaseesh Srivastava

Abstract


 For equipment, systems, and devices with moving structures, fracture is a frequent failure mode. Mechanical overload, mechanical shock, fatigue, or stress corrosion may be the underlying cause of mechanical fracture. Atomic or molecular bond separation leads to mechanical fracture of a material. A concentrated effort to ensure operational safety without a catastrophic fracture failure is known as fracture control. Understanding how cracks affect a structure's strength and integrity as well as how long a fracture can continue to expand before it becomes too large is necessary. The degree to which a component is vital, the financial impact of having the structures out of service, and the potential damage from a fracture failure all factor into the systematic process of fracture control. This article examines the ideas of damage tolerance analysis and outlines the fundamentals of fracture control. It also offers helpful advice on how to apply damage tolerance analysis to get pertinent and fair results. Information on fatigue design and fracture mechanics is provided in the article's conclusion.
