Mechanics of Fiber Reinforced Polymer Composite Structures

Learners enrolled: 811
This is introductory course on Mechanics of Fiber Reinforced Composite Structures. One course is basically aimed at introducing the students of mechanical/civil engineering streams to the basics of design and analysis of structural components made of FRP composites. The contents of the course is so designed that it requires the first course on Strength of Materials/ Solid Mechanics as a prerequisite which is anyway a core course for mechanical/civil undergraduates. It introduces the students first to the basic mechanics (stress strain and load deformation relations) of fiber composites, possible failure modes and corresponding failure theories proposed. Next, the course introduces the design and analysis using those concepts along with the design of some components made of such materials. At the end a few topics of slightly advanced nature (for UG students) are kept for brief introduction only.

INTENDED AUDIENCE  :  Undergraduate and postgraduate students of Mechanical/ Civil/ Aerospace Engineering and similar branches; Faculty members associated with Mechanical/ Civil/ Aerospace Engineering; Practicing engineers associated with design of composite structures.

PRE REQUISITE  :  No specific pre-requisite. Fundamental knowledge of Strength of Materials / Solid Mechanics.

  • 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.


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.
