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 (using conventional engineering terminology and nomenclature) from a narrative describing component loading and geometry.
2. Explain the mechanisms of fracture, fatigue, corrosion, and creep, discuss relevent material properties and apply predictive equations.
3. Carry out calculations to find forces, moments, stresses and deflections for simple beam elements under point, distributed and moment loads.
4. Carry out calculations to find stress and strain in simple elements under elastic loading including shafts in torsion
5. Run an experiment, present and interpret data and commmunicate results verbally and in technical report formats

Indicative Content and Learning Activities

Overview of Design to avoid Failure
A revision of concepts: force, stress, strain, elasticity. Review of engineering material properties and introduction to the main failure mechanisms.

Fast Fracture Failure
Stress concentration, Energy approach to crack growth, Fracture Mechanics

Fatigue Failure
Micro-mechanisms of fatigue, test methods, data presentation and predictive equations

Time Dependant Failure Mechanisms
Creep: Stress – time – temperature relationship, creep rupture testing. Failure by corrosion: Common corrosion reactions, forms of corrosion, materials loss rates.

Elastic Failure
Analysis of a simple beam element : bending moments and shear forces, bending stress theory, deflection of a beam. Torsion of solid and hollow circular shafts.
