| 151-0353-00L | Mechanics of Composite Materials | 4 credits | 2V + 1U | P. Ermanni | |
| Abstract | 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. | ||||
| Learning objective | 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. | ||||
| Content | The course is addressing following topics: - Introduction - Elastic anisotropy - Micromechanics aspects - Classical Laminate Theory (CLT) - Failure hypotheses and damage analysis - Analysis and design of composite structures - Draping effects - Special topics | ||||
| Lecture notes | Script, handouts, exercises and additional material are available in PDF-format on the CMASLab webpage resp on moodle. https://moodle-app2.let.ethz.ch/course/view.php?id=2610 | ||||
| Literature | The lecture material is covered by the script and further literature is referenced in there. | ||||
| 151-0364-00L | Lightweight Structures Laboratory   Number of participants limited to 24. | 4 credits | 5A | M. Zogg, P. Ermanni | |
| Abstract | 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. | ||||
| 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 2-2 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 - Report The project work is supported by selected teaching units. | ||||
| Lecture notes | handouts for selected topics are available | ||||
