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