Vibration and Structural Dynamics

Vibration and Structural Dynamics. Instructor: Prof. Mira Mitra, Department of Aerospace Engineering, IIT Kharagpur. 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 to deliver problem solving capabilities, both for industrial problems and academic research. The course will start from the basics of vibrations and gradually deal with more complex problems. (from nptel.ac.in)
