Course description and aims
This course gives fundamental theories and analytical methods for mechanical disturbances in solids like vibrations and elastic waves. In addition, various engineering applications related to wave theories will be presented.
Theories of vibrations and elastic waves are useful in various engineering fields, including structural dynamics, seismic engineering, ultrasonic nondestructive testing and so forth. This course aims to teach students basic mathematical theories of vibrations and waves in solids, and to suggest a unified approach to other wave phenomena, including acoustic waves and electromagnetic waves.
Student learning outcomes
By the end of this course, students will be able to:
1. Explain mathematically basic wave phenomena, including propagation, reflection, transmission, dispersion and scattering of waves.
2. Solve simple problems of one dimensional waves analytically.
3. Demonstrate wave phenomena of two or three dimensional waves using computational calculations.
4. Explain applications of vibrations and elastic waves in various engineering fields.
