Abstract
The upper-shelf dynamic fracture properties of a low-strength high-toughness steel, A533 Grade B
Class 1, have been investigated with a coupled pressure bars techniques, using small compact
specimens. Toughness data were generated from numerical simulations with a dynamic viscoplastic
finite-element fracture code. The dynamic ductile fracture process was found to involve a larger
critical microstructural distance than that associated with quasi-static loading conditions.
