At the tip of a propagating crack, the stress field becomes singular - and diverges to infinity. In reality, this divergent stress is regularized, as material failure occurs; furthermore, the nature of the singularity at the crack tip can be …
We propose a novel, flexible and easy-to-implement single-camera microscopic three-dimensional digital image correlation (3D-DIC) technique for accurate full-field shape, motion and deformation measurements at the microscale. The established …
