Strength of Materials I

Strength of Materials I

Code	14650
Year	2
Semester	S2
ECTS Credits	6
Workload	PL(45H)/T(30H)
Scientific area	Mechanics and Structures
Entry requirements	Statics and Continuous Solid Mechanics.
Learning outcomes	The curricular unit has the aim to provide training in the following domains: - mechanical properties of materials; - characteristics and geometrical properties of cross-sections; - calculation of stresses due to the four internal forces in linear members; - criteria for yielding and failure for ductile materials; - verification of safety for the resistance limit state; - energetic theorems. Students should develop the following competences: a) to design linear members under axial force in iso/hiperstatics structures; b) to calculate the geometrical properties of cross-sections; c) to design and verify the safety of beams under bending, shear and torsion; d) to calculate displacements on trusses; e) to calculate the equivalent stress according to yielding criteria.
Syllabus	1 - Introduction to Strength of Materials; 2 - Linear members under axial force; 3 - Geometrical properties of cross-sections; 4 - Energetic methods; 5 - Linear members under torsion; 6 - Linear members under bending moment and shear.

Teaching Methodologies and Assessment Criteria	The course is structured with theoretical classes – T (exposition of the subjects and presentation of examples) and practical classes – PL (application of theoretical concepts to solve problems). The evaluation is performed in two stages: - Continuous evaluation (AC): The Continuous Evaluation (AC) is based on the mandatory completion of: i) practical works (TP), ii) a global theoretical-practical test (testTP) without consultation. The TP will be provided throughout the semester with delivery dates to be defined by the teacher. The AC final grade (up to a max. 20 points) will be calculated as follows: AC = 0.2 TP + 0.8 testTP - Exam: Global theoretical-practical exam without consultation, with a maximum grade equal to 20 points.
Language	Portuguese. Tutorial support is available in English.
