Аliieva L. І., Levchenko V. M., Aliiev I. S., Kartamyshev D. O. The development of triangular kinematic module to calculate the deformation pressure in extrusion processes
 article presents universal developed on basis energy upper bound method, designed for use mathematical simulations combined processes cold forging. In particular, this can be used force regime simulating and tool loads analyzing at radial-forward hollow products with blind hole continuous workpieces describe zones during metal flow center turn from radial backward one. kinematically possible velocity field convex curvilinear (parabolic) equations its parabolic inclined boundary are given. Analytical dependencies power forces, friction shear boundaries module, as well reduced a parametric form obtained. which makes it increase efficiency method studying extrusion, has been tested described. It is shown that value most affected by relative thickness flange, radius, wall tubular workpiece, conditions. possibility correct using analysis complex schemes several demonstrated. simulation calculation workpiece variable flange height was carried out. determined due reducing jump boundaries, reduce estimate comparison variants were previously based rectangular modules.
