Teaching methods and learning activities

The curricular unit works in the weekly regime of theoretical classes with a duration of 1h, and a practical laboratory class of 2h.

Theoretical classes introduce the main concepts. The practical classes are taught in DEMec laboratories, where students use the equipment available to solve the problems presented.

It is sought to familiarize the student with specific problems of selection and applications of ceramic and polymeric materials. In the classes of ceramic materials, work is carried out on identification, characterization and processing of ceramic materials. In the chapter of the polymers, work is carried out on the identification and mechanical characterization of different types of polymeric materials. Visits may be made to companies that use the studied materials.

The students can seek support by the teachers throughout the semester to allow the clarification of doubts about the program content and the execution of the reports and experimental activities.

Eligibility for exams

Students will only be able to obtain approval in the CU as long as they reach a classification of at least 40% for each part (ceramic materials 8/20 and polymeric materials 12/20).

Calculation formula of final grade

The evaluation consists of two mini-tests (1 for ceramics and 1 for polymers) and practical work (groups of 2/3 students) about identification and processing of the materials taught, and bibliographic research work.

Ceramic materials: 
8/20 values: Mini-test (25%); Experimental activities (75%).

Polymeric materials: 12/20 values
12/20 values: Mini-test (25%); Experimental activities (75%).

Mini-tests: Minimum value 6.8 in 20 values

Note:

• In order to carry out practical work, presence in practical laboratory classes is mandatory.


• Students who miss classes of a practical work, will be penalized in the final grade of that project.


• If a student miss a class, to make up for this absence (and respective penalty), can attend another class corresponding to that work, as long as the teacher authorizes it.

Classification improvement

Only the mini-tests part can be improved

Observations

Students who did not pass the CU (RFC and RFE) in the previous academic year, only take the mini-test(s) of the part(s) in which they did not obtain a minimum grade (6.8 values), with the final classification being calculated with the work carried out in the previous academic year (this situation is only valid for two academic years).
These students should not register for classes, but should attend theoretical classes at the most favorable time.
