Fracture, Fatigue and Failure of Materials

By Prof. Indrani Sen | IIT Kharagpur

Learners enrolled: 560

ABOUT THE COURSE:

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.

INDUSTRY SUPPORT: Any companies/Industries related to materials for instance Tata Steel, Tata Metallics.

Prof. Indrani Sen

IIT Kharagpur

Prof. Indrani Sen is an Associate Professor at the Department of Metallurgical and Materials Engineering, IIT Kharagpur. She graduated (with a Doctoral degree) as an AICTE sponsored National Doctoral Fellow from the Department of Materials Engineering, Indian Institute of Science, Bangalore in 2010. Prior to that, she completed M.Tech. from IIT Kharagpur (2005) and received the Institute silver medal as the topper from the Materials Science Center. Following Ph.D., Dr. Sen pursued post-doctoral research at Chemnitz University of Technology, Germany and has bagged the prestigious Alexander von Humboldt (AvH) Fellowship. She also held visiting faculty and Av-Humboldt renewed research stay positions at University of Tennessee, USA (2016) and Ruhr University, Bochum, Germany (2018) and achieved Venus Internal Women Award-2018 for outstanding contribution in the field of Materials Engineering. Dr. Sen has made some notable contribution in the field of fracture, fatigue and failure of different category of conventionally produced, thermomechanical processed as well as state of the art additively manufactured materials which are promising candidates for aerospace, marine and biomedical applications. So far, she has managed to showcase her research globally through various National and International conferences as well as well reputed International Peer Reviewed Journal publications including Acta Materialia, Scripta Materialia, Materialia etc. and book chapter.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.

The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).

Date and Time of Exams: 30 October 2022 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.

Registration url: Announcements will be made when the registration form is open for registrations.

The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.

Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.

Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur. It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
