| Abstract: | Based on the theory of similarity, the similarity criteria for experimental and computer simulation of plastic forming are derived with both the linear and exponential work-hardening behavior of materials taken into account. The conditions for approximate simulation with different strains between the original and the model are discussed. The difference between the singularity criteria for computer simulation by small strain theory and that by finite strain theory is analyzed. The experimental and numerical results of a U-shaped piece are given as an example. |
