Solid mechanics is concerned with the stressing, deformation and failure of solid materials. This unit conveys some of this fundamental knowledge related to the analysis and design of engineering structures. It builds on aspects taught in the level 1 unit ENG1001. Topics covered include; bending moment diagrams of determinate and indeterminate beam/frame systems, the calculation of normal stresses due to combined bi-axial bending and axial forces (including those resulting from thermal loading); partial and fully plastic section moment capacities; torsion, shear stress and shear flow in beams; and the calculation of deflections in simple determinate beams. The theory of elasticity is then introduced covering; stress and strain at a point, the transformation of stresses and strains and the calculation of principal stresses and strains; the constitutive relationship between elastic stress-strain behaviour; Mohr's circle; and failure criterion with specific reference to pressure vessels.
At the successful completion of this unit you will be able to:
- Analyse structural behaviour (in the form of bending moment diagrams and deflected shapes) of simple determinate and indeterminate beam and frame systems using qualitative and quantitative methods.
- Identify and determine elastic normal stresses, shearing stresses and shear flow in simple structures as a result of external (including thermal) loading producing internal actions of axial force, bending, torsion and shear.
- Determine the partial plastic and fully plastic section moment capacities of both symmetrical and asymmetrical steel sections.
- Determine the displacement of linearly elastic simple beam systems.
- Determine stresses and strains (and their relationship) in two dimensions utilising the concepts of principal stress and Mohr's circle, and select and use appropriate failure theories for engineering materials.
- Formulate technical reports and communicate effectively in team assignments, interpreting and analysing experimental data, utilising basic analysis software packages and relating results to the theory taught.
Continuous assessment: 50%
Examination (2 hours): 50%
Students are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.
