Abstract：
|
|
It is of great importance that determination of the stress in slip line field to study of metal forming. In comparison with the computation point by point according to Hencky stress equations, determination of the stress in slip line field by use of the geometrical mapping is more visual, clear and simple. In this paper a linear mapping in(σm/k-ω) plane is suggested by author. The basic theory, procedure of drawing and some examples in the application of this geometrical mapping are discussed. Moreover, it is compared with Prager's construction which was based on the cycloid locus of the pole.
