Апстракт
Workability of materials is the possibility of permanent changes in shape and dimensions of workpieces without cracking or other forms of damage to the structure. This property, which numerically valorized by size of limit effective strain, depends on type of material, the initial structure and processing conditions. This paper shows results related to the defining of FLD in bulk metal forming processes, based on theapplication of various theoretical approaches for determining of mean values of ß – factor and strainlimit.
