Arora, PR and Raghavan, MR and Prasad, YVRK (1988) Effect of Prestrain on Fracture Toughness of Rolled Mild Steel with Significant Inclusion Content. In: Journal of Testing and Evaluation, 16 (3). 298 -304.Full text not available from this repository.
The basic method of JIc calculation using a single specimen is discussed. Dokouipil's approach for evaluating the JIc value is extended further and the effect of prestrain on rolled mild steel with significant inclusions is studied using this modified approach. Although this method does not give an accurate value of JIc, it is quite effective for a comparative study. While the fracture toughness of annealed and 7% prestrained materials are about the same, the fracture toughness of 3% prestrained material is significantly lower.
