Course Objective

This course is of particular importance to the practicing engineer because it presents various methods of treating eigenvalue problems for which exact solutions do not exist, or are not feasible. It should be pointed out that the vast majority of continuous systems lead to eigenvalue problems that do not lend themselves to closed-form solutions, owing to non-uniform mass or stiffness distributions. Hence, quite often one is forced to seek approximate solutions of the eigenvalue problem. The methods used are based on energy of the system.

Learning Outcomes of the Course Unit

1   To formulate equations of motions of vibration systems
2   To realize approximate methods to determine the natural frequencies of mechanical
3   To formulate the finite element model of a structure
4   To solve the equations of motions of Holonomic and Non-holonomic systems
5   To make the Eigenvalue analysis
