WM3D3-15 Stress Analysis
Introductory description
Stress analysis is a key tool to investigate the functionality of components/structures under external loading. It also considers using new materials, optimised geometries or a combination of both to improve safety and/or reduce the cost of components.
Students will learn the relevant theories and will be able to apply them to solve engineering problems. They will also be able to apply subject knowledge in a real-world scenario, analyse and present the results.
Apprenticeship Standards ST0025 and ST0027.
This module is linked with C1, C2, C3, C4, C13 and C16 of the AHEP 4 standards.

Module aims
This module aims to enable the participants to determine the response of components/structures to external mechanical stimuli, the resulting deformations and states of stress and strain.
They also learn to predict and prevent common forms of mechanical failure in engineering components.
The module will enable the participants to distinguish whether analytical stress analysis methods are appropriate or numerical simulations are required for any specific component.
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 the 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 and Stress transformation
- Failure criteria

- Introduction to the numerical methods (e.g., FEA) for Stress Analysis
Learning outcomes
By the end of the module, students should be able to:
- Identify existing loads on components/structures as well as the state of stress in complex loadings including axial, shear, torsion, bending, or a combination of them. [AHEP:4-C1, C2, C3]
- Evaluate safety and/or critique design of components and structures under given external loading by application of appropriate stress analysis techniques. [AHEP:4-C1, C2, C3, C4]
- Select appropriate materials relevant to design specifications of the product/component, and draw accurate conclusions from data/test evidence. [AHEP:4-C4, C13]
- Design components based on mechanical failure criteria in a wide range of industrial sectors. [AHEP:4 - C2, C3, C4, C13]
- Demonstrate the ability to function effectively as an individual, and as a member or leader of a team in stress analysis and mechanical design projects [AHEP:4 - C16]

Subject specific skills
Basic knowledge on interpreting stress-strain curves, recognising type of loading and state of stress/strain on parts/components. Predict/prevent structural failure in engineering components. Selection of materials for structural design.
Observe, record and draw accurate and auditable conclusions from data or developmental or test evidence (S5 PD&D, S5 ME).
Comply with statutory and organisational safety standards and requirements, supporting safety risk assessments and mitigate any risks identified within the design (S7 PD&D, S8 ME).
Identify resources, such as digital tools or technologies, human, equipment, materials or data, to complete design and development projects or programmes of work (S8 PD&D, S9 ME)
Evaluate engineering designs, development, or modification options (S13 PD&D).
Transferable skills
-Problem-solving: Use rational and logical reasoning to deduce appropriate and well-reasoned conclusions.
Retain an open mind, optimistic of finding solutions, thinking laterally and creatively to look beyond the obvious.
Knows how to learn from failure.
-Teamwork: Operate within, and contribute to, a respectful, supportive and cooperative group climate. Sensitive
to the impact of actions on others.
-Critical Thinking: Recognise patterns, themes and key messages from sometimes confused and incomplete
data. Make informed decisions on the value of a range of sources allowing an evidence based conclusion
based on this analysis.
-Information Literacy: Critical awareness of how information is gathered, used, managed and synthesised.
Understanding of the relative value of different sources and the importance of provenance. The systematic
collection, analysis and evaluation of information in the investigation of a topic.
