# Detailed module information

Module information on this degree can be found below, separated by year of study.

The module information below applies for the current academic year. The academic year runs from August to July; the 'current year' switches over at the end of July.

Students select optional courses subject to rules specified in the Mechanical Engineering Student Handbook,  for example at most three Design and Business courses. Please note that numbers are limited on some optional courses and selection criteria will apply.

## Stress Analysis 2

### Module aims

This course builds on the ME1 Stress Analysis Course by extending the concepts of linear elasticity to two and three dimensions, as the basis for advanced stress analysis.

Topics covered include complex stresses and strains, Mohr’s circle, failure criteria, shear stresses in beams, thick-walled cylinders, plastic failure and buckling of struts. The course should enable students to develop sufficient familiarity with stress analysis and strength of materials to design a safe and reliable load-bearing component of simple geometry (or to assess the safety of an existing one).

ECTS units: 5

### Learning outcomes

To demonstrate an understanding of how stresses at a point vary and combine in different directions.

To demonstrate the ability to use direct stress and shear stress transformation and related equations along with a mathematical understanding of how these equations arise.

To use and understand Mohr's circle to represent complex stresses and strains and solve problems.

To show an  understanding of and ability to apply different failure criteria for ductile and brittle materials, along with an appreciation of safety factors.

To understand and solve problems involving stress variations in beams and thick-walled pressure vessels.

To demonstrate the ability to solve problems involving elastic-plastic, fully-plastic bending and residual stress behaviour in beams.

To demonstrate the ability to derive and use Euler buckling theory for different boundary conditions.

To demonstrate the ability to use Finite Element Method software to solve simple problems.
