Aerospace Structural Analysis

By Prof. Mira Mitra | IIT Kharagpur

Learners enrolled: 3346 | Exam registration: 188

ABOUT THE COURSE:
The objective of the course is to learn the principles of solid and structural mechanics that can be used to design and analyze aerospace structures. Aerospace structural analysis is a fundamental course dealing with analysis of thin walled aircraft structures required for design of aerospace vehicles. The course primarily discusses analysis of thin-walled aircraft structures under torsion, shear and bending loads from the concepts of theory of elasticity. It also discusses stability and buckling of aircraft structures.

INTENDED AUDIENCE: Undergraduate/Post-Graduate Students and Professionals working in Aerospace Industries

PREREQUISITES: Third year undergraduate students with prior knowledge of solid mechanics/strength of material can successfully do this course

INDUSTRY SUPPORT: Any aerospace industries like Airbus/Boeing/GE/L&T/Relevant DRDO/CSIR Labs.

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: 28 April 2024 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 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.
