Paper Abstract

In this paper, deformed cross gratings around crack-tip are recorded. The derivative fields of displacements (∂u/∂x, ∂u/∂y, ∂v/∂x, ∂v/∂y, ∂w/∂x ∂w/∂y) are obtained by optical spatial filtering of two shifted deformed gratings. From which, strain contours around crack-tips can be obtained directly.
