Determination of Tensile Properties of Polyester - Industrial Waste Red Mud Composites Using Digital Image Correlation (DIC)

The Digital Image Correlation (DIC) technique is an important method of evaluating material strain fields. Composite materials have inherently heterogeneous elastic properties, in the function different phases present composition, whereat traditional techniques deformation evaluation may not be sufficient to determine mechanisms that eventually contribute failure material. work were evaluated, tensile mechanical properties polyester matrix composites loaded with industrial residue red mud, a mass fraction 20%. surveyed using conventional gauge and compared data obtained through DIC. results showed DIC was accurate monitoring displacements determining average tested specimens, addition providing ample fields, for throughout sample request process.
