摘要

It has been proposed in the literature in the last few years that a room temperature charpy test (referredrnto as PAC by Dr. Norman Brown) can predict Small-Scale Steady-State (S-4) rapid crack propagationrn(RCP) behavior . This paper explores the proposal further and presents findings demonstrating that arncorrelation between PAC (Pennsylvania Accelerated Crack) and S-4 is not particularly strong. Rather, itrnis found that the Charpy ductile to brittle transition temperature (Tdb) provided for a much betterrncorrelation to S-4.
