Experimental data obtained from 25 mm thick Comsteel En25 compact tension specimens tempered from the as-quenched state to 650Β°C showed that the ASTM Standard, E399-74, specimen size and plasticity requirements were not able to detect excessive yielding and thus the onset of true plane-strain condit

Al~traet--Fracture Mechanics of Ductile Metals (FMDM) theory is used to obtain the plane strain fracture toughness, K~, for different materials. The traditional approach for obtaining the K~ value is to conduct several standard tests on cracked plates that are costly and time consuming. The fracture
Fracture toughness testing in the transition region often causes ductile tearing to precede cleavage fracture. The effect of ductile tearing on the fracture probability has in recent years become a subject of great interest. Briickner and Munz have developed a Weibull statistics based model to descr
