Open Source ↗
In finite element-based digital image correlation (FE-DIC) with unstructured triangular meshes, accurate evaluation of image-based integrals is critical to robustness and measurement accuracy. Two evaluation point generation strategies are investigated herein, namely, a pixel-based approach and a me
