Abstract
This paper investigates the applicability of the proposed digital image
correlation (DIC) system instead of traditional method by microscope to
measure the strains in forward extrusion process, which conducted for
rectangular 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 to
measure the strain and strain rate for the forward extrusion process by a
visio-plasticity technique and the proposed digital image correlation
system. The obtained results indicate that the proposed digital image
correlation (DIC) system is an accurate and reliable for measuring the
strains using inexpensive equipments
