WM3D3-15 Stress Analysis
Introductory description
To design new products or optimise existing ones, stress analysis is a key tool to investigate the possibility of using new materials, new geometries or a combination of both.
Module aims
By continuing the applications of the mechanics of materials theories, the participants acquire the ability to determine the response of structures to external mechanical stimuli, the resulting deformations and the state of stress and strain produced in the components of structures. They also learn to predict and prevent common forms of structural failure in basic engineering components. This module deals with knowledge of stress analysis as applied to the design of mechanical systems within the automotive, aerospace and product development industry. It will enable the participants to carry out both analytical and numerical methodologies while enhancing their capabilities in utilising engineering packages.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
- Revision of Theory of Stress and Strain
- Torsion of Shafts
- Analysis and Design of Beams for Bending
- Multi-axial loadings and complex states of Stress
- Principal Stresses / Stress Transformation
- Failure criteria
- Mechanical / Material testing for Stress / Strain Analysis
- Introduction to Fracture Mechanics
- Fatigue Failure Analysis
- Numerical Methods for Stress Analysis
Learning outcomes
By the end of the module, students should be able to:
- Appreciate the concepts of stress and strain as a result of external loadings/deformations on mechanical parts and components
- Implement stress analysis approach to design based on failure criteria for structural analysis or product development in a wide range of industrial sectors
- Develop an industrial-oriented application of the principles of static and strength of materials on stress analysis and apply them to solve analytical solutions to axial, bending, shear and combined loadings.
- Critique designs based on the stress analysis approach .
