FRACTURE DEVELOPMENT AND MATERIAL PROPERTIES IN PVRC-PENN STATE PRESSURE VESSEL.

Abstract

A characterization of materials was conducted in relation to the terminal, burst-type, failure of a PVRC pressure vessel in A212A steel at 110F. Materials were characterized with respect to chemical composition, tensile properties, fracture toughness including Charpy-V and Tear Energies, Drop-Weight NDT, micrography and electron fractography. The initiation and growth of a 34-in. long fatigue crack was shown to be caused by mechanical aspects rather than material deficiencies and the plastic instability burst, brittle run, and crack arrest were in complete accord with the Fracture Analysis Diagram.
