Abstract

The digital image correlation approach for strain assessment is a non-contact approach. The goal of this study was to measure the strain of the carbon fiber layer by non-contact method. The goal was to see how well a strain measuring method worked by analysing photos taken with a DSLR camera. The photos of carbon fiber layer processed with the Mathlab R2021a programme. The change in length in the y coordinate of the photographs was used to determine strain. The experimental and literature values were found to be in good agreement. The modulus of elasticity of the stell of the carbon fiber layer was estimated from the strain curves, and the findings were compared by the value given by universal testing machine (UTM) by doing tensile test. The findings show the results of the carbon of the carbon fiber layer’s strain measurements by using Ncorr Matlab.
