Introduction To Crystal Elasticity And Crystal Plasticity

By Prof. Swarup Bag   |   IIT Guwahati
Learners enrolled: 28
This course is primarily designed based on students who are interested in physics based model in broad area of materials and manufacturing processes. The aim of this course is to bridges the gap between continuum mechanics and material science where the behavior is described at different length scales.The course emphasizes on basic understanding of the related topics by mathematical and physical problems involved in studying mechanical behavior of conventional metals and alloys. Students will be able to develop fundamental understanding on the response of common engineering materials to mechanical loading at different length scales through the lectures and will be reinforced through assignments. The course is highly enjoyable to the beginners as it will be presented in most simplified way.

INTENDED AUDIENCE : Bachelor/Master/PhD students having background in Mechanical/Materials/metallurgical/Chemical engineering/Physics

PREREQUISITES : There are no pre-requisites in educational qualification.The knowledge in the courses like Solid Mechanics and Engineering Materials are added advantage

Instructor bio

Prof. Swarup Bag

IIT Guwahati
The broad area of instructor is teaching and research interest of materials and manufacturing processes through computational models using finite element method and experiments. The instructor completed his Ph.D on “Development of bi-directional heat transfer and fluid flow model for reliable design of GTA and laser welding processes” from Indian Institute of Technology Bombay. Later he has worked at the Center for Material Forming (CEMEF), MINES Paris Tech, France in Metallurgy, Structure and Rheology (MSR) group. Soon after post-doctoral research experience, he joined in the Department of Mechanical Engineering, Indian Institute of Technology Guwahati as a faculty member. His primary area of research is fundamental process modeling of welding and joining technologies, optimization of manufacturing processes and recrystallization in metal forming processes. Dr. Bag has published about 56 journal papers, 45 Conference papers, and 18 book chapters related to welding and joining processes. He is the author of the book ‘Computational models for GTA and laser welding processes’ and recipient of ‘Royal Arc Award 2009’ from Indian Institute of Welding for the best PhD thesis in welding. The instructor is involved in teaching the subjects like ‘Physics of Manufacturing Processes’, ‘Engineering Materials’, ‘Advanced Welding Processes’, ‘Mechanical Behavior of Materials’, ‘Solidification Processes’ and ‘Manufacturing Technology’ at IIT Guwahati. The subjects broadly covers the fundamentals of manufacturing processes, mechanical metallurgy, theory of plasticity, heat transfer in manufacturing processes, crystallography, dislocation mechanism, phase transformation and solidification.

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: April 24, 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 6 assignments out of the total 8 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 Guwahati.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.
