The lightweight design philosophy and the application of strength of materials principles in lightweight design – Design principles. Analysis of thin-walled members with closed or open cross section – shear center – warping and distortion, torsion-bending problems of thin bodies. Analysis of thin-walled pressure vessels under internal / external pressure, bending disturbances due to geometrical discontinuities. Shear flow theory – analysis of beam shear in closed or open cross-section, multiple-web beams, flat or curved members. Simplified analysis of aeronautical structures (fuselage – wing under bending, torsion and shear, wing ribs). The principle of virtual work – The unit load method. Maxwell-Mohr method. Applications in aeronautical and lightweight structures.
