From the photograph, crack opening displacements (COD) are measured in the vicinity of the crack tip, and the dynamic fracture toughness K_\u003cID\u003e is calculated through the formula of COD in the singular stress field of a propagating crack. Two types of optical systems are used for holographic recording of cracks. The values of K_\u003cID\u003e obtained through one optical system are in agreement with those obtained through the other. One of the holographic optical systems can simultaneously record the caustic of a fast propagating crack at a moment when the crack tip is recorded as a hologram. The value of K_\u003cID\u003e caluculated from COD measurement is roughly in agreement with that from the caustic method.", "subitem_description_type": "Abstract"}]}, "item_10001_description_6":
