Dynamic J sub I-R Curve Testing of HY-130 Steel.

Abstract

The J-integral crack growth resistance properties of HY-130 steel were developed under dynamic loading conditions. The objective of this program was to extend the key curve method to evaluate ductile fracture properties of HY-130 steel compact specimens where the loading rate produced a load-line crack-opening displacement rate on the order of 9-inches per second. A key curve for HY-130 plate was developed under dynamic loading conditions using subsized specimens and was applied to tests of 1TCT Specimens. Results of ambient temperature tests showed that both J sub Ic and the tearing modulus of this steel were substantially elevated under dynamic loading. The fracture process of specimens tested under dynamic and static loading conditions was found to be similar and completely ductile. (Author)
