Description This is a core module for all mechanically based engineering degrees. It underpins decisions made in design, and provides a foundation for more advanced analysis techniques and tools. | |||||||||||||||||||||||||||||||||||||||||
Learning Outcomes 1. Devise an appropriate calculation from a narrative describing component loading and geometry including simple components under axial, torsion, bending,pressure and thermal loading. 2. Carry out calculations to find stress and strain in simple elements under elastic loading including pressure vessels and struts 3. Explain how stress can be transformed (in 2D) and apply transformation equations and Mohr's circle. 4. Apply yield criteria to calculate limits on simple components under multiaxial loading 5. Apply a systematic approach to the selection of a material, i.e. mathematically represent a mix of property requirements for particular applications and design goals, and then use material selection charts to identify a subset of suitable materials 6. Incorporate into material choice tools consideration of the phase of material lifecycle contributing most to environmental impact. 7. Run an experiment, present and interpret data and communciate results verbally and in technical report format | |||||||||||||||||||||||||||||||||||||||||
