Abstract:

The principal aim during the first year of investigation was to develop a theoretical method of analysis for obtaining the detailed mechanics of the extrusion process, with special reference to extrusion through conical dies. The visioplasticity and upper-bound methods were summarized, and the method of calculating temperature distributions was reviewed. Extended treatment of admissible velocity fields was then made, and a numerical method was developed for predicting the non-steady-state temperature distributions. A computer program of the entire procedure was completed for general use. Author
