The course is specially designed for postgraduates (MSc and PhD) to gain the ability to solve vibration problems using appropriate deterministic or statistical methods. By providing the theoretical background of these methods, the course helps students to understand the principles of different vibration analysis methods and their limitations. Higher frequency vibration analysis of complex structures, for which traditional deterministic methods, such as finite element (FE) methods, are not suitable, is particularly addressed in the course. The theoretical background and assumptions of Statistical Energy Analysis (SEA), as a power tool for solving high frequency vibration problems, are introduced.
