151-0525-00LWave Propagation in Solids4 credits2V + 1UJ. Dual, D. Mohr
AbstractPlane 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.
ObjectiveStudents 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.
ContentWave 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.

151-0735-00LDynamic Behavior of Materials and Structures
Does not take place this semester.
4 credits2V + 2UD. Mohr
AbstractLectures and computer labs concerned with the modeling of the deformation response and failure of engineering materials (metals, polymers and composites) subject to extreme loadings during manufacturing, crash, impact and blast events.
ObjectiveStudents will learn to apply, understand and develop computational models of a large spectrum of engineering materials to predict their dynamic deformation response and failure in finite element simulations. Students will become familiar with important dynamic testing techniques to identify material model parameters from experiments. The ultimate goal is to provide the students with the knowledge and skills required to engineer modern multi-material solutions for high performance structures in automotive, aerospace and navel engineering.
ContentTopics include viscoelasticity, temperature and rate dependent plasticity, dynamic brittle and ductile fracture; impulse transfer, impact and wave propagation in solids; computational aspects of material model implementation into hydrocodes; simulation of dynamic failure of structures;
