Invalid fracture toughness data have been analysed using a semi-empirical fracture formula, which has been applied to invalid bend and compact tension specimens made of various steels, and thin centre-cracked panels made of aluminium alloys. Reasonable estimates of the toughnesses were obtained in ...

The cracked chevron-notched Brazilian disc (CCNBD) was proposed by the International Society for Rock Mechanics (ISRM) to test the mode I (opening mode) fracture toughness of rock. The test method has been vigorously discussed and debated, despite being the subject of intensive research for deca...

Plane strain fracture tests provide additional important data. Following Bridgman 's stress analysis inside the necking of a plane strain specimen, a closed-form solution is derived for the stress triaxiality inside the notch of a flat-grooved plane strain specimen. The newly derived formula is ...
The straight-through cracked three-point bend round beam specimen is a new kind of fracturetoughness specimen[1 ～3]. In this paper,the J-integral estimation formula for this kind of specimen is formulated un-der the condition of contained plasticity. The method of formulation proposed by Zahoor...
