Aims

The aims of the course are to:

  • Provide students with an understanding of how the stresses and strains within engineering components are related to both the loads and displacements imposed at their boundaries and to any thermal or inertial loadings to which they are subjected.
  • Introduce analytical methods, predominantly for two-dimensional geometries, and for both elastic and plastic material responses.
  • Illustrate the methods with a number of engineering case studies.

Objectives

As specific objectives, by the end of the course students should be able to:

  • Calculate the stresses in an elastic or plastic axisymmetric system subjected to various loads.
  • Use Airy and Prandtl stress functions to find analytical solutions to elastic problems.
  • Apply upper- and lower-bound theorems to solid mechanics problems.

Coursework

Experimental Stress Analysis

Use experimental techniques to determine the stress concentration at the edge of a circular hole in finite plates.

Learning objectives: 

  • To develop an appreciation of errors that occur in experimental measurements of stresses using different experimental techniques.
  • To learn about Digital Image Correlation.
  • To note that the stress concentrations are sensitive to the location of the hole in the plate.
  • To compare measured concentration factors with simple analytical predictions.

Introduction to the Manufacturing Engineering Tripos (MET)

Overview

MET is an option for the final two years of the Cambridge Engineering degree that develops and applies engineering knowledge in a business context.  MET aims to prepare students to operate professionally as broadly-based leaders for business and technology, by giving them a thorough grounding in management and manufacturing technology, together with an understanding of the full range of activities from market analysis through product design and production, to sales and distribution.

Part IIA Options Offered by the Engineering Department - Limitations on the choice of modules: Engineering Areas

If you wish to qualify in an Engineering Area, at least six modules from your total of ten must fall within one of the Engineering Areas  as defined by the Faculty Board of Engineering.  A definitive list for the coming year will be available to you in the Easter term prior to you making your provisional selection on COMET.  You may choose to qualify only in 'Engineering', which means that you may choose any combination of modules (subject to restrictions on sets described below, the requirement
