DIC1D: A MATLAB-Based 1D Digital Image Correlation Analysis Tool

Introduction A MATLAB program called DIC1D will be presented in this talk as a valuable tool for both novice and experienced users of digital image correlation (DIC) analyses in accurate and reliable whole-field deformation measurement applications. The need for speedy calculations and better spatial resolution favors a smaller subset size, while a higher signal-to-noise ratio and more accuracy in displacement measurements usually requires a larger subset size and higher-order subset deformation mapping functions in a DIC analysis. The DIC1D program aims to serve as a simple learning and teaching tool to help a user to identify the crucial characteristics of a digital image pair and the proper selection of DIC analysis parameters to achieve the optimal balance between these two conflicting requirements.
