Teaching method

 

The basic concepts about structure and properties of materials are presented during the theoretical lectures in such a way that they can be dealt by the resolution of numerical problems during TP lectures which are taking place during the first 10 to 11 first weeks. These concepts are afterwards consolidated by laboratory sessions where the student performs practical works focussing on the structural characterization of materials and the determination of some mechanical properties (last 4 to 5 weeks).

The last 2 theoretical lectures are devoted to the presentation of case-studies of failure analysis, as well as to the illustration of the Materials Selector Program (from Ashby).

Evaluation method

To obtain frequency it is necessary :

- to attend the theoretical lectures,

- to attend the practical sessions,

- to have the practical reports (from laboratory sessions) approved.

Final grade of the discipline is the result of the final examination (for those students who obtained frequency)
