Dynamic Properties of Materials. Part 2. Aluminum Alloys

Abstract

A literature survey on the mechanical properties of aluminum alloys under dynamic loadings has been made. The experimental data showing the variation of yield, ultimate strengths and elongation with strain rate and temperature are compiled and tabulated. The range of strain rate included in this report is from 0.00001 in/in/sec to 10,000 in/in/sec, while the temperature range is from -300 deg F to 900 deg F. The variations of yield and ultimate strengths are plotted for 6061 and 7075 aluminum alloys. It is shown that both the yield and ultimate strengths are higher under dynamic loads than under static loads. However, the aluminum alloys are not as strongly affected by strain rate as polymers and steels. It is also shown that the yield and ultimate strengths decrease with an increase of temperature.
