Plane Flow Analysis for a Profile Extrusion Die Using Digital Image processing Technique

Abstract

This paper investigates the applicability of the proposed digital imagecorrelation (DIC) system instead of traditional method by microscope tomeasure the strains in forward extrusion process, which conducted forrectangular section with plane strain condition by using taper die at angle(2 = 90 ̊) and the proportion of reduction in area is (42.85 %).Commercial pure lead (99.99% Pb) was chosen as a typical pattern tomeasure the strain and strain rate for the forward extrusion process by avisio-plasticity technique and the proposed digital image correlationsystem. The obtained results indicate that the proposed digital imagecorrelation (DIC) system is an accurate and reliable for measuring thestrains using inexpensive equipments
