An experimental technique for studying dynamic fracture toughness under stress wave loading is described in this paper. With a Bar Impact Testing Machine, the three point bending specimen was fractured under impact loading, the loading rate K, being approximately lo6 N/mm3'2. s. An accurate measurem

Abatraet-Generally, linear elastic fracture mechanics (LEFM) is inadequate for fracture toughness (&.) characterizations of brittle or quasi-brittle materials such as ceramics, concretes, and rocks, because large process xones exist. In order to obtain a valid, size independent Xr, value (or to sati
The relationship between the three point bend (TPB) specimen size and the measured fracture toughness K,, value is analyzed by the theory of crack opening displacement (COD). According to the concept of plane strain fracture toughness K,,, a new formula for K,, is presented. For small-scale or large
Abslgact--An experimental technique for determining fracture toughness K~c and its confidence has been suggested. The Kanninen's solutions of the stress intensity factor K and the displacement A at loading points for the double cantilever beam (DCB) specimen has been simplified analytically. Accordi
