Learning Achievement

Students after learning this course should know how to derive the constitutive laws for materials and have the ability to derive the equations of motion based on the Hamilton's principle for continuous structures.

Students are taught to perform theoretical analysis of vibration and wave motion of structures. They would be well trained with the knowledge of suppressing the vibration and noise of structures by the means of different passive and active feedback-control techniques together with sensors and actuators.

Various applications from sensors to actuators are introduced and their working principles will be interpreted.
