Advanced Structural Analysis

1. Computation of structural deflections for thin-walled structures - continuation. (Applying the Dummy Unit Load Method, computation of relative displacements). 2. Analysis of Statically Indeterminate Structures. (External vs internal redundancies, multiple redundancies, applications to wing and fuselage structures). 3. Engineering theory of bending for open and closed tubes an overview. (General stress, strain and displacement relationships for open and closed tubes). 4. Shear flow in open and closed tubes. 5. Twist and warping of shear loaded closed tubes. 6. Displacements associated with the Bredt-Batho shear flow. 7. Warping distribution of a doubly symmetrical rectangular closed tube subjected to a torque. 8. Warping of open tubes. 9. Axial constraint stresses in open tubes. (The Wagner torsion-bending theory, calculation of the torsion bending constant, the wire analogy for flat sided sections). 10. Axial constraint stresses in closed tubes. (Doubly symmetrical single cell, 4-boom tube under torsion). 11. Shear diffusion. (Axial constraint stresses in a doubly symmetrical single cell 6 stringer tube subjected to a transverse shear force). 12. Elements of plate bending theory. (Kirchhoff assumptions, equilibrium equations via the stationary value of the potential energy, Kirchhoff derivation of the boundary conditions, simply supported rectangular plate under sinusoidal loading, Navier solution for simply supported rectangular plates,
