Some Practical Aspects of Digital Image Correlation Technique to Evaluate Anisotropy Coefficient and Its Comparison with Traditional Method

CODEN: JTEVAB

Abstract

Digital Image Correlation (DIC) is a robust method that is used to evaluate full-field displacements. In this technique, images taken from the specimen are compared before and after deformation; this method provides an accurate displacement field as well as strain values. The objective of the present work is to examine the DIC method using the traditional method of calculating the plastic anisotropy coefficients. In this research, the DIC method has been applied on one side of the specimen, and the conventional circle grid analysis technique is performed on the other side. Results showed that the fully automated 2-D DIC method in MATLAB (MathWorks, Natick, MA) was verified and that it could replace the traditional technique of circle grid analysis, which is time consuming and incurs a lot of human errors.
