Objectives
The main goal of the course is to give an insight to materials structure-properties relationship, with enphasis on materials for biomedical applications.
Prerequisites
None
Subject matter
Theorectical topics:
1. Materials classificatiion. Biomaterials and biocompatibility.
2. Metalic and Ceramic materials: Crystal structure and crystal geometry; X-ray diffraction; Crystalline imperfections.
5. Phase diagrams.
4. Polymeric Materials.
5. Mechanical properties of materials
6. Linear Viscoelasticity.
7. Rubber elasticity.
8. Elasticity of biological tissues: the formation of an aneurysm - analogy with rubber elasticity.
Lab classes:
1 - Synthesis of PMMA and Nylon 6-10
2 - Tensile tests of a metal and a polymer: Analysis of the stress-strain curve.
3 - Rubber elasticity (Gough-Joule effect, uniaxial and biaxial tensile tests).

Teaching method
Two tipes of presencial classes: Lectures (2h/week); Practical (2 h/week). Lectures will be supported by powerpoint slides.
Tuturial classes are also available every week (2 h/week) for supporting the students in there homework.
Evaluation method
Evaluation has 3 components:
1 - Individual Quiz Tests concerning Lab activities (MTL);
2 - Reports (RAL) of lab activities. These are group reports;
3 - 2 Tests (TP) or a Final Exam (EF) covering lecture topics. Minimum grade = 8.0 (out of 20).
Approval in the course depends on the presence in all lab classes (mandatory) and MTL grades higher than/or equal to 9.5 (out of 20).
Final grade is obtained by:
i) 0,15*MTL+0,25RAL+0,60*TP (TP is the average of the grades of the 2 tests);
or
ii) 0,15*MTL+0,25RAL+0,60*EF
