✦ Synopsis

A&act-This paper examines 3 theories that have been used to character&e the arrest capabilities of steels and structures: (1) The static analysis, arrest toughness W,*) theory; (2) The dynamically loaded/stationary crack toughness t&d) theory, and (3) The dynamic analysis, propagating crack energy or toughness (R,,, or KID) theory. These three concepts arc examined in the iiht of measurements of unstable fracture and crack arrest in wedge-loaded DCB test pieces together with a fully dynamic analysis of the experiments.
