Aims & Learning Objectives:
To teach appropriate techniques for the loading, stress analysis and failure prediction of aircraft structures.
After taking this unit the student should be able to:
Determine critical gust and manoeuvre load cases.
Design aircraft structures by accounting for static strength, buckling and fatigue failure.
Use, and have a basic understanding of, computer packages for structural analysis and design.
Content:
Gust and manoeuvre envelope. Shear force, bending moment and torque diagrams. Shear flow and shear centre of open and close sections. Fracture strength and crack propagation, including safe-life and damage-tolerant design. Shear buckling and tension fields - analysis and design of ribs and spars. Compression buckling of stiffened panels - analysis and design of wing and fuselage panels. Use of computer packages for structural analysis and design.
