Study of transverse strain near tip of crack type Ⅰ using holographic interferometry |
| |
| Abstract: | On the basis of the theory of holographic interferometry and fracture mechanics, the transveres strain at the tip of crack typeⅠ is studied. With the holograph of the strain field of crack tip,the strain curves are quantitatively analyzed,and the results are basically in agreement with the data obtained by fracture mechanics. |
