Contribution of the course to the program objectives

Having regard to the LO of the programme KIMA, this activity contributes to the development and acquisition of the following LO:

• LO 1.1, 1.2
• LO 2.1, 2.2, 2.3, 2.4, 2.5
• LO 4.1, 4.2, 4.4
• LO 5.1, 5.2, 5.3, 5.4, 5.6

Specific learning outcomes of the course

At the end of this course, the student will be able to

• LO1.1. Explain the basic concepts of the materials selection procedure established by Prof M.F. Ashby: property charts, the formulation of selection problems in terms of - function, objectives, constraints, free variable - using performance indices, multiple and/or conflicting objectives, shape and hybrid solutions, eco-design;
• LO1.1. Describe modern material solutions which more and more consist of multimaterials systems, comprising composites, multilayers, coatings, assemblies, functionalized surfaces.
• LO1.2 Use the material selector software EDUPACK edited by Granta design;
• LO2.1 to 2.5. Apply the material selection procedure to real problems (case studies) which involve the analysis of the problem (i.e. define the list of requirement by decomposition into the elementary functions in order to define the working conditions and function, main solicitations, objectives and constraints), the derivation of performance indices, the selection of the best solution, the justification of the simplification, the critical assessment of the solution and the formulation of better solution compared to existing solution ' all these steps will require mobilizing all their scientific and technical knowledge gained in earlier training regarding physical phenomena and all the classes of materials.
• LO4. Organize the analysis of the last case study as a team project effort
• LO5. Communicate and defend the results of the case study analysis

The students will be individually graded based on the objectives indicated above. More precisely, the evaluation involves the grading of

• the presentation of two case studies already solved in the supporting book by group of two;
• the presentation of a new material selection problem by group of two;
• a written exam based on a short list of synthetic questions prepared by the teachers and given during the year

This course is very much based on personal learning. The method proposed by M.F. Ashby in his book 'Materials Selection in Mechanical Design' is followed with a few additional or more in depth information such as for instance about hybrid materials. About 9 lectures are proposed to cover the main aspects of the procedure, mixed with exercise sessions and case study analyses. Lots of room is left for discussion. The students will receive a license to use material selector software by Granta design. Additional resources are provided on icampus.

The book « Materials Selection in Mechanical Design » par M. Ashby (4eme édition, Elsevier) is a compulsory support of the course

This course requires only basic knowledge of materials science in particular regarding the mechanical properties (elasticity, plasticity, fracture, basic structural mechanics) and functional properties (electrical, thermal, optical, magnetic).
