| Abstract: | The similarity conditions for simulating rigid-plastic deformation are deter-mined based on the similarity theory and a model proportionately reduced in size is selected, by which computer simulation for the plastic forming process has been carried out. Two examples are given, one of the upsetting of cylinder and the other of plane strain. |
