Soil Dynamics

By Prof. Paramita Bhattacharya   |   IIT Kharagpur
Learners enrolled: 63
The course is designed for the UG students interested in advanced level of Geotechnical Engineering, PG students and research scholars of Geotechnical Engineering and other relevant specialization of Civil Engineering. The practicing engineers in the field of Civil and Geotechnical Engineering may also be benefited from this course. The objective of the course is to understand the fundamentals of vibrations, response of soils and foundations under dynamic loadings and design criterion of foundations subjected machine vibration and earthquake loading. For this purpose, theory of vibrations, response of single and multiple degree of freedom undamped and undamped systems under free and forced vibrations, dynamic properties of soils say, dynamic shear modulus, elastic modulus, damping ratio etc., liquefaction potential and design of machine foundations will be discussed.

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 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.
