MEEN30020 Mechanics of Solids II

Academic Year 2022/2023

Syllabus:
Introduction to 2D states of stress and strain: stress transformations, principal stresses, maximum shear stress, Mohr's circles of stress and strain, Hooke's law. Strain measurement using strain gauge rosettes. Thin walled pressure vessels.
Introduction to 3D states of stress and strain. Mohr's circle in 3D. Combinations of axial, torsional and bending loading. Yield criteria.
The use of the Unit Load energy method in structural analysis.
Torsion of non-circular sections. The Prandtl stress function. Analysis of solid elliptical, rectangular, narrow rectangular and developed cross-sections, and thin-walled closed cross-sections.
Introduction to fatigue analysis of shafts subjected to a combination of bending, torsion and axial loading.

Laboratory Exercises:
Lab 1: One of the following experiments will be performed by a given group:
(a). Experimental verification of the maximum shear stress yield criterion for a ductile metallic test specimen subjected to combined bending and torsional loading. OR (b). The use of the Unit Load energy method to determine deflections in structures subjected to bending loads.

Lab 2: Introduction to finite element stress analysis. Determination of the state of stress in a typical engineering structure or component.

Note: Lab reports are to be handed in within two weeks after the date of the lab activity.

Assignments: Two homework assignments will be set during the course of the trimester. Students will typically be given two weeks to complete each assignment.

Recommended Texts: Benham, P. P., Crawford, R. J. Armstrong, C. G., Mechanics of Engineering Materials, 2nd edition, Prentice Hall, 1996.

Learning Outcomes:

On successful completion of this subject the student will be able to:
1. Analyze 2D states of stress and strain, sketch Mohr's Circles and calculate principal values and corresponding principal directions.
2. Analyze 3D states of stress and strain, sketch Mohr's Circles and calculate the principal values and corresponding principal directions of stress and strain tensors.
3. Confidently analyze the state of stress caused by a combination of axial, torsional and bending loads and determine the resulting factor of safety against yielding.
4. Calculate the required diameter or the factor of safety of a shaft subjected to fatigue loading.
5. Perform a finite element stress analysis of a simple engineering component.
6. Present and justify the main assumptions and findings in formulating and solving the stress analysis problems encountered in the course.

Approaches to Teaching and Learning:
A problem-based approach is taken in lectures, whereby the theory is taught through examples. In addition, a comprehensive book of course notes is provided which contains many worked examples, including recent examination papers, which allow students to master individual topics at their own pace. Online teaching tools in the form of screencasts are also provided for some topics. The lecturers are very approachable and are always available to meet with students to discuss any topic for which they require further clarification.

Feedback Strategy/Strategies

• Feedback individually to students, post-assessment
• Group/class feedback, post-assessment

How will my Feedback be Delivered?

In-Class Tests & Brightspace Quizzes: Grade will be posted automatically on submission of quiz. Laboratory Reports: Will be submitted via Brightspace and a short individual feedback will be provided (also via Brightspace) by the teaching assistant in charge of the lab. Final Examination: Individual feedback will be provided on request after the release of final grades for the module.
