Estruturas Aeroespaciais

Objectives

This course aims the acquisition of methodologies and the development of capabilities for structural analysis and modelling of aircraft components, in any flight condition or maneuver, in the scope of its design and sizing. To this end, it envolves: - The understanding of fundamentals of structural analysis and energy methods applied to bending, shear, torsion and instability of thin-walled beams, as well as to bending, vibration and instability of thin plates; - The use of methodologies for stress analysis of aircraft components and its modelling, namely, fuselages, wings, wing spars and wing ribs, under diffent types of loadings, applying theoretical knowledge in design calculations, including computational approaches, as necessary for design and sizing of aircraft structural components.
