Numerical Simulation of Severe Plastic Deformation of Titanium Specimens under Dynamic Channel Pressing

Abstract:

Deformation processes of the α-titanium specimens moving through the channels of the die for two loading schemes: equal channel angular pressing (ECAP) and channel pressing through the channel of variable form (CVF) are investigated. Schemes of dynamic pressing in case the block is extruded at high speed through the channel of the die due to the pressure of the punch or the pressure of powder gases were analyzed. The problem is solved by the smoothed particle hydrodynamics method (SPH) within the framework of elastoplastic continuum.
