| 151-0079-30L | Airborne Wind Energy System - Ftero 3 This course is part of a one-year course. The 14 credit points will be issued at the end of FS2019 with new enrolling for the same Focus-Project in FS2019. For MAVT BSc and ITET BSc only. Prerequisites for the focus projects: a. Basis examination successfully passed b. Block 1 and 2 successfully passed For enrollment, please contact the D-MAVT Student Administration. | 0 credits | 15A | P. Ermanni | |
| Abstract | Students develop and build a product from A-Z! They work in teams and independently, learn to structure problems, to identify solutions, system analysis and simulations, as well as presentation and documentation techniques. They build the product with access to a machine shop and state of the art engineering tools (Matlab, Simulink, etc). | ||||
| Learning objective | The various objectives of the Focus Project are: - Synthesizing and deepening the theoretical knowledge from the basic courses of the 1. - 4. semester - Team organization, work in teams, increase of interpersonal skills - Independence, initiative, independent learning of new topic contents - Problem structuring, solution identification in indistinct problem definitions, searches of information - System description and simulation - Presentation methods, writing of a document - Ability to make decisions, implementation skills - Workshop and industrial contacts - Learning and recess of special knowledge - Control of most modern engineering tools (Matlab, Simulink, CAD, CAE, PDM) | ||||
| 151-0353-00L | Mechanics of Composite Materials | 4 credits | 2V + 1U | G. Kress, P. Ermanni | |
| Abstract | Modelling of stiffness and strength of fiber-reinforced plastics and laminates made thereof as well as simple structures is considered. For free-edge effects and periodic structures numerically efficient FEM approaches for generalized plane strain and unit-cell modelling are explained. Finally, the mechanical interpretation of experimental measurement results is treated. | ||||
| Learning objective | The objective is to impart understanding of the mechanical response of structures made from anisotropic and heterogeneous fiber-reinforced composite materials with all the peculiarities which are not known from metals. The course shall incite fascination with the multifaceted and exciting modelling questions in this field, providing a basis for research. On the other hand the course provides qualification for composite-materials product development within an industrial environment. | ||||
| Content | 1. Introduction and elastic anisotropy 2. Laminate theory 3. Thick-walled laminates and interlaminar stresses 4. Edge effects at multidirectional laminates 5.

| 151-0364-00L | Lightweight Structures Laboratory  | 4 credits | 5A | M. Zogg, P. Ermanni | |
| Abstract | Teams of 2 to 4 students have to design, size, and manufacture a lightweight structre complying with given specifications. A prototype as well as an improved component will be tested and assessed regarding to design and to structural mechanical criteria. | ||||
| Learning objective | To develop the skills to identify and solve typical problems of the structure mechanics on a real application. Other important aspects are to foster team work and team spirit, to link theoretical knowledge and practice, to gather practical experiences in various fields related to lightweight structures such as design, different CAE-methods and structural testing. | ||||
| Content | The task of each team (typically 2-4 students) is the realization of a load-carrying structure with selected materials. The teams are free to develop and implement their own ideas. In this context, specified requirements include information about loads, interface to the surrounding structures. The project is structured as described below: - Concept development - design of the component including FEM simulation and stability checks - manufacturing and structural testing of a prototype - manufacturing and structural testing of an improved component - Report The project work is supported by selected teaching units. | ||||
| Lecture notes | handouts for selected topics are available | ||||
