Plates and Shells

By Prof. Sudip Talukdar | IIT Guwahati

Learners enrolled: 319

Plates and shells exhibit two dimensional structural actions that result in stronger, thinner and lighter structures and therefore, have economic advantage. This has opened the scope for the wide use of such elements in all fields of engineering due to significant increase of strength/weight ratio. This course is usually taught in Master’s degree level either as separate elective subject or including some principal topics in Continuum Mechanics. The exposure to this course and its completion are very essential in understanding the behaviour of thin structures for their applications in design. The proposed course is framed for post graduate level elective subjects for 12 weeks duration. The syllabus includes various topics of the linear elastic plate and shell theories, formulation of problems for different load cases and boundary conditions, finding closed form solutions and discussions of their limitations. The approximate methods, in case the closed form solutions are not available have also been included in the syllabus.

The course is divided into 12 modules in which each module consists of 3 or 4 lecture hours. The assignment after the end of each module in MCQ/ Fill in the blanks or problem solving mode will be offered to the participants and asked to submit for evaluation. Evaluation is planned in off-line mode.

INTENDED AUDIENCE : Master degree/ PhD students

PRE REQUISITE :BE (Civil/ Mechanical/ Aerospace Engg)

SUPPORTED INDUSTRIES : Aeronautics Research & Development Board, Delhi; Indian Space Research Org., Bangalore

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 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.
