Fracture, Fatigue and Failure Of Materials
Prof. Indrani Sen · IIT Kharagpur
About
The course is designed to implement the theoretical knowledge about the mechanical behavior of material, particularly focusing on fracture mechanics and fatigue characteristics to understand, assess and overcome failure. Both the linear-elastic as well elastic-plastic fracture mechanisms will be discussed. This will be followed by discussing the characteristics and mechanisms of fatigue cracks initiation and propagation. Importance of microstructure and environment in controlling the performance of materials will also be highlighted. Next, concepts will be developed on failure and methods for root cause analysis. The course will be equipped with necessary and appropriate schematic representation and case-histories in association with the required lectures on fundamental concepts. Participants will acquire a state of the art knowledge on the broad field of fracture and fatigue and their implementation in failure analysis of materials.
Intended audience: Final year UG and PG students and PhD research scholars from various disciplines like Materials and Metallurgical Engineering, Materials Science, Ceramic Engineering, Nanoscience and Nanotechnology.
Prerequisites: Any introductory courses on (a) Materials Science and Engineering, (b) Mechanical behavior of materials.
