2D Finite-element-based global DIC method (guarantee global kinematic compatibility and decrease noise by adding regularization penalties).
2D_FE_Global_DIC MATLAB code was tested on MATLAB versions later than R2018a. Please download and unzip the code to the MATLAB working path. Then, execute the mail file main_FE_Global_DIC.m.
It is already included in the code. It's also available at my Researchgate: https://www.researchgate.net/publication/345907429_Finite_Element_Global_Digital_Image_Correlation_FE-Global-DIC_Code_Manual_v10
2D_FE_Global_DIC MATLAB code demo is very similar to the ALDIC code:

I also attach my EASF webinar to introduce AL-DIC/DVC algorithm and review other DIC/DVC methods:
