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
The evaluation of the curricular unit (UC) has two components:
1 - Practical evaluation, given by the evaluation of the laboratory notebook (LN): 40%
2 - Theoretical assessment (60%), comprising different assessment elements:
2.1. The newspaper (NP) of the curricular unit (10%) (group activity);
2.2. Two summative tests (T) or Final Exam (FE), which focus on the subjects taught in theoretical and theoretical-practical classes (50%) (Minimum average of 8 values)
Attendance to ALL laboratory activities is mandatory, so the student will be excluded in case of absence.
- Students who opt for the final assessment will have access to the exam, provided they have attended ALL lab classes.
- The final grade is given by:
i) 0.40*LN+0.10*NP+0.50*TA; for students that attended ALL lab classes and opt for continuous assessment (TA represents the arithmetic mean of the two tests)
or
ii) 0.40*LN+0.10*NP+0.50*FE; for students that attended ALL lab classes and opt for the final exam.
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.
9. Composite materials.
Lab classes:
1 - Diffraction experiments
2 - Physical properties of materials/Determination of the porosity of a ceramic
3 - Polymer synthesis
4 - Tensile tests of a metal and a polymer: Analysis of the stress-strain curve.
5 - Analysis of the creep behavior of a polymer.
6 - Rubber elasticity (Gough-Joule effect, uniaxial and biaxial tensile tests).
