Statistical Analysis of Estimated Displacement Measurements using Digital Image Correlation

Kavita Tewari, Ramesh Kumar Kulkarni

Abstract


This paper presents details of the statistical analysis of the estimated displacements on a sample of pearlitic steel. It is mostly used in construction, automobiles, and industries.   The displacement measurement of deformation is computed in the horizontal and vertical direction with pixel accuracy. Digital Image Correlation (DIC) is a non-contact technique to estimate u and v displacement. The deformation of the sample is computed using NCORR software. Detailed statistical analysis has shown that the displacements have a strong correlation between them.
