Research of the stressed and deformed state of metal stripin the broaching process

In papers [2,4,5] the solution relations and algorithm of method block iterations solving linear nonlinear equations by semivanalytic finite element for curvilinear inhomogeneous prismatic bodies are realized. paper [1], a numerical study convergence solutions was performed, wide range test problems with smoothly abruptly changing physical geometric characteristics in elastic resilient-plastic formulation considered. [6], to confirm reliability results obtained on basis semi-analytical method, effectiveness this approach calculation objects is shown. Solving control theory elasticity, thermoelasticity thermoplasticity, as well shape change makes it possible draw conclusions about selected class based developed methodology implements its application package.
 work, using outlined above works, spatial problem plastic deformation body solved elements, process broaching strip metal embossing analyzed. The purpose determine picture stress-strain state during drawing compare resolution flat one. A comparison parameters workpiece process, settings, allows us conclude that research must be carried out calculation.
