https://doi.org/10.22349/1994-6716-2025-122-2-50-61
Abstract
Influence investigation of the angular die parameters on hydrostatic pressure during equal channel angular pressing was studied by finite element method. The channel intersection angle has been considered in the range 90–120°, and the outer die radius was studied in the range (0.05–1). The problem is solved under the assumption of а plane-strain state using a model of an ideal rigid-plastic body. The friction conditions with the coefficient of friction equal 0.1 are determined by Coulomb – Amonton’s law. The results of modeling the level of hydrostatic pressure on the axis of the deformation zone are compared with the analytical solution. The hydrostatic pressure distribution dependence at the input and output of the plastic deformation zone boundaries on the die geometry characteristics was estimated. The hydrostatic pressure heterogeneity in plastic deformation zone was determined.
