Teaching method

 The base concepts on the structure and properties of the diferente classes materials are presented in the theoretical-practical classes so that they be treated through examples. These concepts are then consolidated through practical laboratory classes where the students complet with additional exercises and performs practical sessions on  the structural characterization of materials and determination of mechanical properties.

 

 

Evaluation method

The evaluation consists of 2 theoretical and pratical written tests . The Evaluation does not exempt performance of all tests as well as the mandatory frequency of laboratory classes. Students wishing to do the course solely by the final examination must attend laboratory classes.
