Mechanical Behaviour of Materials
The subject aims at providing students with knowledge on:
- mechanical properties of major groups of materials in engineering;
- phenomenological aspects of plasticity;
- mechanical tests;
- concepts and applications of fracture mechanics, fatigue and creep;
- criteria for creep and fatigue design;
- concepts of stress corrosion.

Students are requested to have completed Materials Science and Solid Mechanics I.
- Jorge Rodrigues e Paulo Martins, Tecnologia Mecânica - vol.1, ed. Escolar Editora, 2005.
- Martins Ferreira, Comportamento mecânico de materiais, ed. FCTUC, 1999.
- Ashby, Michael F., Jones, David R.H., “Engineering Materials 1: An introduction to their properties and applications”, 2nd Edition, Butterworth Heinemann, 1996.
In lectures the material is presented and discussion is promoted. There is some lab work to promote the contact of the student with a variety of experimental equipment.
Option 1: Continuous Evaluation
- 1st Test (in person, if the pandemic situation allows it);
- 2nd Test (in person, if the pandemic situation allows it);
- Case study with report, presentation and discussion.
Final grade = 1st Test x 0.35 + 2nd Test x 0.35 + Case study x 0.30
with 2nd Test >= 8.0 values.
To obtain frequency, the student must have at least 9.5 values in the Case study. Students with frequency in the previous academic year (2019/2020) are automatically admitted to evaluation this year.
The student will be approved if the Final grade is equal to or greater than 9.5 values while have frequency to the discipline.
If the student has a Final grade equal to or higher than 18 values, an oral exam will be held to defend the grade.
Option 2: Final Exam
All students with frequency to the discipline have access to the final exam.
The exam has a minimum grade of 9.5 values.
The exam will be in person, should the pandemic situation allows it.
The grade of the Case study will be taken into account if:
Final Exam x 0.70 + Case study x 0.30 > Final Exam,
provided that the grade of the final exam is > = 9.5 values.
The student will be approved if the grade of the final exam is equal to or higher than 9.5 values while have frequency to the discipline.
If the student has a final grade equal to or higher than 18 values, an oral exam will be held to defend the grade.
If the student fails, the grade of the case study will remain valid for 1 academic year.
