Objectives

This course has as a main objective the study of the interaction between materials and their environment, focusing on the cases where the interaction leads to degradation of the materials properties, compromising their performance and/or leading to environmental problems.

The course uses most of the background from previous courses, namely on the structure and properties of metals, polymers and ceramics, that the sudent should use in order to understand the materials/environment interactions.

The final goal of the course is that the student becomes able to antecipate the interaction between a certain material with its environment

Teaching methods and learning activities

The subjecst are presented to the students in an interactive way, always having in mind the engineering cases and applications.

There will be three mini-tests. The students will make a presentation to the colleagues, in groups of three, about a topic related with materials degradation

- the student should make a presentation of a work

Calculation formula of final grade

Final Grade = 0.60NEF + 0.20NmT + 0.15*NAp

NEF: grade obtained in the final exam. It should not be inferior to 9V
NmT: grade obtained in the mini-tests
NAp: grade obtained in the presentation of the work in the class+abstract

Examinations or Special Assignments

not applicable

Internship work/project

not applicable

Special assessment (TE, DA, ...)

It will consist of a writen exam about all teached subjects

Classification improvement

As approved by the Faculty of Engineering for all the courses.
