Workability Theory of Materials in Plastic Deformation Processes.

摘要

The investigation is aimed at establishing a workability criteria in upsetting and rolling with reference to occurrence of free surface cracks. A review of the background on workability is given,indicating the need for methods of analysis which provide the required information on the mechanics in metal-working processes. The development of such a method is described. With this method,the workability criterion of SAE 1040steel in upsetting,based on the observed fracture condition,is described. Although workability in rolling was not examined in this investigation,it appears possible by the developed theory to construct a workability criterion also in rolling. (Author)
