The program listed in this appendix was designed principally for demonstration purposes and to form an introduction to non-linear FE plasticity analyses. In order to simplify the approach, only constant-strain triangular elements have been used. The program is sufficiently flexible, however, to be able to deal with plane-stress, plane-strain and axi-symmetric examples.

The data contained within the sub-program FILDATA are specifically for sticking-friction axi-symmetric upsetting. It should be a simple matter to change the appropriate entries to tackle different problems. Comment statements are used liberally throughout the program in order to try and explain what is happening at each stage. The programs could have been written in a more condensed and efficient form, but the format given here was chosen deliberately to allow the reader and potential user to follow the program structure and operation as easily as possible.
