TIME-DEPENDENT COMPRESSION PROPERTIES OF ALUMINUM ALLOY 2024-0 AT 500 F (533 K)

Abstract

Compression creep and compression constant strain-rate tests were performed on thick wall cylindrical specimens of aluminum alloy 2024-0 at 500F (533K). Using the assumption that the equation of state of the material is a function only of stress, strain, and strain rate, the creep curves were analyzed to yield constant strain-rate, stress strain data. Comparisons between the creep-derived and the directly measured constant strain-rate data show that the data are not exactly equivalent but the discrepancies are sufficiently small so that to a first approximation the equation of state assumption can be considered valid. The data presented will be utilized in the next state of the investigation, to develop theoretical results for the Gerard Theory of Time Dependent Plastic Stability for comparison with experiments now in progress.
