Unit Description and General Aims
This unit deals with advanced topics in mechanics of materials. The constitutive relations of elastic media are introduced and applied to analyse plane-stress problems: deep beams, corbels and torsion of thin-walled beams. Then, the deformations of beams in torsion are elaborated including uniform torsion, stresses and deformations due to warping, non-uniform torsion and the effects of diaphragms on the deformation of closed sections.
Bending, twisting and deflections of thin flat plates is studied and applied to deduce the differential equation of plate bending. Elastic plates and slabs are analysed by analytical and numerical techniques.
Plastic mechanisms are studied to determine ultimate load capacity of continuous beams, frames and isotropic and orthotropic slabs.
On successful completion of this Unit, students are expected to be able to:
- Formulate plane-stress structural cases and apply this knowledge to analyse 2D structures.
Bloom’s Level 6
- Determine the different modes of torsional deformation and the corresponding stress distributions and apply this knowledge to analyse open and closed sections with different deformation conditions.
Bloom’s Level 5
- Formulate the Differential Equation of bending of thin plates to analyse elastic plates:
- Rectangular and circular isotropic plates.
- Bridge decks.
Bloom’s Level 6
- Evaluate structures using plastic methods. Determine ultimate loading and plastic mechanisms by incremental and / or energy methods for cases of:
- Beams using incremental and energy methods;
- Frames using energy methods;
- Slabs using the yield line energy method.
