Was used hardening curve set as an exponential dependence proposed by Alyaev-Smirnov [8]: , (10) where is the intensity of the stress; is the degree of deformation; М, С, В, N are coefficients determined in the test material for linear tension (compression).
The values found for the minimum deformation work Аmin to determine efforts hex head bolts reduction from different materials with different size ratio.
The following conditions were adopted: isothermal process, the plastic material of the work piece, the plasticity condition according Huber-Mises, hard tools, the material for the work piece is steels G15240 and C1035, the tool dimensions was designed for punching the flange bolt M10, the coefficient of friction was assigned.
