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 aims to provide training in the following areas: - mechanical properties of materials; - geometric characteristics and properties of cross sections; - calculation of stresses due to 4 internal forces in linear parts; - yield and rupture criteria for ductile materials; - safety check in relation to the limit state of resistance; - energy theorems. It is intended that students obtain the following skills: a) understand the mechanical behavior of materials, in a fundamental approach to the concept of resistance, stiffness, yielding and rupture; a) design bars subjected to axial stress inserted in iso/hyperstatic structures; b) calculate the geometric properties of cross sections; c) dimension and check the safety of beams subjected to bending, shear and torsion; d) determine displacements in trusses; e) calculate the reference stress using the yield 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	Classes are organized into theoretical classes – T (exposition of the syllabus, also involving the presentation of examples) and practical classes – PL (application of the syllabus through the resolution of practical problems). In all components, experimental demonstrations are used based on tests of reduced models, which take place according to explanatory needs. Part of these experimental activities are included in evaluative activities.
Language	Portuguese. Tutorial support is available in English.
