151-0525-00LWave Propagation in Solids4 KP2V + 1UJ. Dual, D. Mohr
KurzbeschreibungPlane Waves, harmonic waves, Fourier analysis and synthesis, dispersion, distorsion, damping, group and phase velocity, transmission and reflection, impact, waves in linear elastic continua, elastic plastic waves, experimental and numerical methods in wave propagation.
LernzielStudents learn, which technical problems must be approached using the methods used in wave propagation in solids. Furthermore, they learn to use these methods and develop an intuitive feeling for phenomena that can be expected in various situations.
InhaltWave Propagation in solids including applications.
Content: Phenomenology of wave propagation ( plane waves, harmonic waves, harmonic analysis and synthesis, dispersion, attenuation, group and phase velocity), transmission and reflection, impact problems, waves in linear elastic media ( P- Waves, S-Waves, Rayleigh waves, guided waves), elastic plastic waves, experimental and numerical methods.
LiteraturVarious books will be recommended pertaining to the topics covered.
Voraussetzungen / BesonderesLanguage according to the wishes of students.
