151-0318-00LEcodesign - Environmental-Oriented Product DevelopmentW4 credits3GR. Züst
AbstractEcodesign has a great potential to improve the environmental performance of a product.
Main topics of the lecture: Motivation for Ecodesign; Methodical basics (defining environmental aspects; improvement strageies and measures); Ecodesign implementation (systematic guidance on integrating environmental considerations into product development) in a small project.
ObjectiveExperience shows that a significant part of the environmental impact of a business venture is caused by its own products in the pre and post-production areas. The goal of eco design is to reduce the total effect of a product on the environment in all phases of product life. The systematic derivation of promising improvement measures at the start of the product development process is a key skill that will be taught in the lectures.
The participants will discover the economic and ecological potential of ECODESIGN and acquire competence in determining goal-oriented and promising improvements and will be able to apply the knowledge acquired on practical examples.

AbstractThis course is offered by the Design and Technology Lab Zurich, a platform where students from the disciplines industrial design (ZHdK) and mechanical engineering (ETH) can learn, meet and perform projects together. In interdisciplinary teams the students develop a product by applying methods used in the different disciplines within the early stages of product development.
ObjectiveThis interdisciplinary course has the following learning objectives:
- to learn and apply methods of the early stages of product development from both fields: mechanical engineering and industrial design
- to use iterative and prototyping-based development (different types of prototypes and test scenarios)
- to run through a development process from product definition to final prototype and understand the mechanisms behind it
- to experience collaboration with the other discipline and learn how to approach and deal with any appearing challenge
- to understand and experience consequences which may result of decision taken within the development process
ContentAt the end of the course each team should present an innovative product concept which convinces from both, the technical as well as the design perspective. The product concept should be presented as functioning prototype.

The learning objectives will be reached with the following repeating cycle:
1) input lectures
The relevant theoretical basics will be taught in short lectures by different lecturers from both disciplines, mechanical engineering an industrial design. The focus is laid on methods, processes and principles of product development.
2) team development
The students work on their projects individually and apply the taught methods. At the same time, they will be coached and supported by mentors to pass through the product development process successfully.
3) presentation
Important milestones are presented and discussed during the course, thus allowing teams to learn from each other.
4) reflection
The students deepen their understanding of the new knowledge and learn from failures. This is especially important if different disciplines work together and use methods from both fields.

AbstractLagrangian dynamics - Principle of virtual work and virtual power - holonomic and non holonomic contraints - 3D rigid body dynamics - equilibrium - linearization - stability - vibrations - frequency response
ObjectiveThis course provides the students of mechanical engineering with fundamental analytical mechanics for the study of complex mechanical systems .We introduce the powerful techniques of principle of virtual work and virtual power to systematically write the equation of motion of arbitrary systems subjected to holonomic and non-holonomic constraints. The linearisation around equilibrium states is then presented, together with the concept of linearised stability. Linearized models allow the study of small amplitude vibrations for unforced and forced systems. For this, we introduce the concept of vibration modes and frequencies, modal superposition and modal truncation. The case of the vibration of light damped systems is discussed. The kinematics and dynamics of 3D rigid bodies is also extensively treated.

- Understanding the importance of material science and metallurgical considerations in MAM,
- Appreciating the importance of thermal, fluid, mechanical and microstructural simulations for efficient use of MAM technology,
- Using different commercial analysis tools (COMSOL, ANSYS, ABAQUS) for simulation of the MAM process.
ContentPreliminary lecture schedule:
- Introduction to MAM (concept, application examples, pros & cons),
- 2x Powder-bed and powder-blown metal additive manufacturing,
- Thermo-fluid analysis of additive manufacturing,
- Continuum-based thermal modelling and experimental validation techniques,
- Residual stress and distortion simulation and verification methods,
- 2x Microstructural simulation (basics, analytical, kinetic Monte Carlo, cellular automata, phase-field),
- Mechanical property prediction for MAM,
- 3x Microstructure and mechanical response of MAM material (steels, Ti6Al4V, Inconel, Al alloys),
- Design for additive manufacturing
- Artificial intelligence for AM
Exercise sessions use COMSOL, ANSYS, ABAQUS packages for analysis of MAM process. Detailed video-instructions will be provided to enable students setting up their own simulations. COMSOL, ANSYS and ABAQUS agreed to support the course by providing licenses for the course attendees and therefore the students can install the packages on their own systems.
Lecture notesHandouts of the presented slides.
LiteratureNo textbook is available for the course (unfortunately), since it is a dynamic and relatively new topic. In addition to the material presented in the course slides, suggestions/recommendations for additional literature/publications will be given (for each individual topic).
Prerequisites / NoticeA basic knowledge of mechanical analysis, metallurgy, thermodynamics is recommended.
