151-0502-00L | Mechanics 2: Deformable Solids and Structures Prerequisite: 151-0501-00L Mechanics 1: Kinematics and Statics This course is only for students of Mechanical Engineering, Civil Engineering and Human Movement Sciences. Students in Human Movement Sciences and Sport must enrol in "Mechanics 1" and "Mechanics 2" as a two-semester course. | 6 credits | 4V + 2U | D. Mohr | |
Abstract | Stress tensor, deformations, linear elastic solids, bending of prismatic beams, numerical methods, bending, torsion, plastic work and deformation energy, energy methods, buckling. | ||||
Objective | For the mechanical design of systems, knowledge about basic concepts of continuum mechanics are indispensable. These include mechanical stress, deformations, etc. which are demonstrated on simple examples resulting in an understanding which is both mathematically correct and intuitive. In this course students learn the basic concepts of the mechanics of deformable media that they will later apply in other courses such as Dimensioning which are closer to real engineering applications. | ||||
Content | Spannungstensor, Verzerrungen, linearelastische Körper, spezielle Biegung prismatischer Balken, numerische Methoden, allgemeinere Biegeprobleme, Torsion, Arbeit und Deformationsenergie, Energiesätze und -verfahren, Knickung. | ||||
Literature | Mahir B. Sayir, Jürg Dual, Stephan Kaufmann Ingenieurmechanik 2: Deformierbare Körper, Teubner Verlag | ||||
151-0735-00L | Dynamic Behavior of Materials and Structures Does not take place this semester. | 4 credits | 2V + 2U | D. Mohr | |
Abstract | Lectures 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. | ||||
Objective | Students 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. | ||||
Content | Topics 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; | ||||
Lecture notes | Slides of the lectures, relevant journal papers and users manuals will be provided. | ||||
Literature | Various books will be recommended covering the topics discussed in class | ||||
Prerequisites / Notice | Course in continuum mechanics (mandatory), finite element method (recommended) |
