Simulation of „Yalle Body” Profile Extrusion

Article Preview

Abstract:

Present paper presents the results concerning the modeling process of extrusion of a profile type “Yalle body”. COSMOS soft was used in order to simulate the extrusion process. 3D model contains elements type SOLID, witch simulates the nonlinear behavior in the field of elasticplastic domain. The constitutive equation of Iliusin and Dracker-Prager relation and Von Misses criterion were used in simulation. The three dimensions model contains 1504 nods and 1750 elements in two different position of the die (optimum position and “out of optimum position”). For both of die positions were presented variation of equivalent total stresses, tangential stresses in different steps (1st step, critical step, and 20th step, by dividing the whole extrusion process in equal steps).
