EG-187 Engineering Analysis for Materials 1
To provide a grounding in engineering analysis methods for materials students. The module will cover the most important analytical functions and methods used in engineering and will relate these to common materials-related examples. The module will ensure the required grounding in methods and techniques for those who have not previously covered this area, or who are returning after a gap. It will also provide opportunities for extension to more complicated examples for those who have more prior experience.
-
EG-262 Stress Analysis 1
This module continues on from EG-120 or EG-131 and includes: section properties; unsymmetrical bending; stresses in thick cylinders; rotating discs; theories of failure; stress concentration effects; fatigue and linear elastic fracture mechanics.
