This course is part of a one-year course. The 14 credit points will be issued at the end of FS2021 with new enrolling for the same Focus-Project in FS2021.
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.
|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).
|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)
|Mechanics of Composite Materials
Number of participants limited to 80.

|Focus is on laminated fibre reinfoced polymer composites. The courses treats aspects related to micromechanics, elastic behavior of unidirectional and multidirectional laminates, failure and damage analysis, design and analysis of composite structures.
|To introduce the underlying concept of composite materials and give a thorough understanding of the mechanical response of materials and structures made from fibre reinforced polymer composites, including elastic behaviour, fracture and damage analysis as well as structural design aspects. The ultimate goal is to provide the necessary skills to address the design and analysis of modern lightweight composite structures.
|The course is addressing following topics:
- Elastic anisotropy
- Micromechanics aspects
- Classical Laminate Theory (CLT)
- Failure hypotheses and damage analysis
- Analysis and design of composite structures
- Draping effects
- Special topics
|Script, handouts, exercises and additional material are available in PDF-format on the CMASLab webpage resp on moodle.
|The lecture material is covered by the script and further literature is referenced in there.
|Lightweight Structures Laboratory
Number of participants limited to 24.
|M. Zogg, P. Ermanni
|Teams of 2 to 3 students have to design, size, and manufacture a lightweight structre complying with given specifications. An aircraft wing spar prototype as well as later a second improved spar will be tested and assessed regarding to design and to structural mechanical criteria.
|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.
|The task of each team (typically 2-2 students) is the realization of a reduced-scale aircraft wing spar, a typical 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
- cost assessment
The project work is supported by selected teaching units.
|handouts for selected topics are available

|The elective course Lightweight includes numerical methods for the analysis of the load carrying and failure behavior of lightweight structures, as well as construction methods and design principles for lightweight design.
|The goal of this course is to convey substantiated background for the understanding and the design and sizing of modern lightweight structures in mechanical engineering, vehicle and airplane design.
