Teaching method
Two types of lessons will be considered: Lectures (theory / practice) and laboratory. The lectures will be given using powerpoint slides and students have access to copies of them on the course page in Moodle. The laboratory work will be performed by the students under the guidance of the teacher and focus on the different types of materials covered in the course.
Evaluation method
The evaluation of the curricular unit (CU) has two components:
1 - Practical evaluation, given by the evaluation of laboratory work reports (R): 35% 2 - Theoretical evaluation (65%), comprising different evaluation elements:
2.1. Activities proposed in the theoretical classes (TA) (15%) (group activity). 4 activities will be proposed, one of which is a research work, with presentation. The AT classification is obtained through a weighted average, where the research work has a weight of 3 and the remaining activities have a weight of 1.
2.2. Three summative tests (T) or Final exam (EF), which focus on the subject taught in theoretical and theoretical-practical classes (50%) (Minimum average of the tests, or minimum exam grade, is 8 points) .
Attendance in laboratory classes is mandatory, so the student will be excluded if absent.
- Students who opt for final assessment will have access to the exam, provided that they attend ALL lab classes.
- The final grade is given by: i) 0.35*R+0.15*TA+0.50*MT; for students who frequently opt for continuous assessment (MT represents the arithmetic mean of the three tests)
or
ii) 0.35*R+0.15*TA+0.50*EF; for students who opt for the final exam.
Subject matter

5. Phase diagrams.
4. Polymeric Materials.
5. Mechanical properties of materials
6. Linear Viscoelasticity.

Lab classes:
1 - Physical properties of materials/Determination of the porosity of a ceramic
2 - Polymer synthesis
3 - Tensile tests of a metal and a polymer: Analysis of the stress-strain curve.
4 - Analysis of the creep behavior of a polymer.
5 - Rubber elasticity (Gough-Joule effect, uniaxial and biaxial tensile tests).
