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).

 

Evaluation method


Admission to final exam does not require obtaining frequency.

Approval in the UC by continuous evaluation requires:

- to attend at least 2/3 of the total practical sessions,

- to attend the laboratory sessions (mandatory),

- attendance of 1 midterm theoretico-practical (TP) quizz, 1 midterm practical (P) quizz and 1 theoretical (T) quiz that will take place according to the scheduling shown in the planning available from CLIP at "Documentação de apoio / Outros", scheduled by the PC

The 3 midterm quizzes have the following weights:

- TP, weight 35%,

- P, weight 30%,

- T, weight 35%

For the final approval by continuous evaluation:

- the first midterm theoretico-practical quizz may not be graded below 7,

- final grade on the continuous evaluation above 9.5 required for final approval.

Final grade of the UC:

- final grade of the continuous evaluation, if above 9.5,

or

- result of the final exam.
