This module has presented different approaches to model plastic flow in metal forming operations, showing their relative importance and limitations. 

The approaches covered are:-

  • Slip line field theory
  • Work formula analysis
  • Limit analysis and hodographs
  • Finite element analysis

The backgrounds to the approaches have been summarised, and then examples presented to show how each can be used in practice to provide estimates of the necessary deformation loads for the various metal forming operations.
