Prerequisites & Installation

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.

Code Manual

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

Code Demo

2D_FE_Global_DIC MATLAB code demo is very similar to the ALDIC code:

Versión Publicado Notas de la versión
1.2.3

(i) Fix the previous bug about "FStrainWorld". Thank Hasan Hamdan and Philip DePond pointed out this bug! (ii) Improve the FE-mesh for Sample 12 example. Thank Prof. David Wootton for pointing out this! https://github.com/jyang526843/2D_FE_Global_DIC

1.2.2

[IMPORTANT]: I correct the inconsistency of computing "FSubpb2World" in the physical world coordinate system. Users who don't use code Sections 5-6 or who don't plot shear strains are not affected. Sorry about the inconvenience.
