Analysis of Crack Arrest Under Elastic-Plastic Conditions

Source

Elastic-plastic finite-element analyses of quasi-static crack propagation and arrest in a compact test specimen are described. The analyses evaluate the effect of the prior plastic deformation history of the propagation event on the shape of the J-resistance curve of the arrestor. In addition, experiments employing a special device are used to simulate fast fracture and arrest in small laboratory test specimens of ductile HY-80 steel and tough 7075 aluminum. The results show that large dynamic elevations of the J-curve are encountered during arrest. A relatively simple procedure for assessing or designing welded-in, steel crack arrestors, based on these findings is proposed.
