Vibration and Structural Dynamics

By Prof. Mira Mitra | IIT Kharagpur

Learners enrolled: 2559

The course aims at imparting fundamentals of vibration and structural dynamics to senior undergraduate and graduate students. The course primarily consists of four modules, namely, single degree of freedom, multi-degree of freedom, continuous system, and analytical methods. The objective of the course is deliver problem solving capabilities both for industrial problems and academic research. The course will start from basic of vibrations and gradually deal with more complex problems.
