Strength of Materials II

Code	14654
Year	3
Semester	S1
ECTS Credits	6
Workload	PL(30H)/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: - Interaction between internal forces; - Biaxial bending with axial force; - Deformation of beams in pure and simple bending; - Stability of columns; - Hiperstatics beams; - Models for non-elastic materials; plastic bending of beams. Students should develop the following competences: a) to calculate reference stresses in cross-sections under combined internal forces; b) to calculate normal stresses in cross-sections with eccentric axial loads and draw the central core; c) to calculate displacements in beam´s structures and design cross-sections through the stiffness criterion; d) to check the safety on linear members under buckling; e) to calculate internal forces in hiperstatic beams; f) to calculate the plastic moment and the collapse load of beams.
Syllabus	1 - Linear members under combined internal forces (M+V+T or N+T); 2 - Linear members under axial force and bending momento (N+M); 3 - Deformation of beam under bending (M or M+V); 4 - Stability of columns; 5 - Statically indeterminate beams; 6 - Elasto-plastic bending of beams.

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 practical works (TP) and a theoretical-practical test (testTP) without consultation. The TP will be provided throughout the semester with delivery dates to be defined by the teacher. The testTP will be performed on 12/12/2023 (Class PL). 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.
