Abstract
We propose a novel scanner-based digital image correlation (DIC) method to determine the full-field in-plane displacement as well as the Young’s modulus of elastomeric materials at strains up to 350%. A low-cost charged-couple device flatbed scannerwas used as the image acquisition device instead of a digital camera in the conventional DIC method. A motorized loading fixture was designed to act as the specimen clamp as well as the tensile load applicator. The rubber specimens weremade according to the ASTM:D412-06a standard andmounted into the fixture. Each specimen was scanned at increasing loads and the images were processed to obtain the full-field displacement maps using incremental cross-correlation algorithm. The Young’s modulus of the rubber at strains of 50–350% obtained using the scanner-based DIC method was compared with those obtained from a universal tensile test machine. The comparison shows a maximum deviation in Young’s modulus of 8.9 at 150% strain. The high-resolution flatbed scanner coupled with the built-in lighting was found to be an effective tool for low-cost DIC application for large deformation materials.
