Abstract:
Tests were conducted to determine the effect of load cycling on creep buckling behavior of metal columns. Two materials were investigated: 2024-T4 aluminum alloy columns with length to radius of gyratioon ratios of 81.2 and 55.7 were tested at 350F and 450F; C-110M titanium alloy columns have a length to radius of gyration ratio of 90 were tested at 700F and 800F. The cycling period used was 24 hours, the time the load was on in that period was the variable. In addition to the cyclic load tests, constant load tests were conducted to obtain background infromation. A linear relationship was found between the time to creep buckling under constant load and the reciprocal of the minimum creep defection rate. This relationship was used in interpreting the cyclic load test results. The effect of load cycling provided to be dependent upon the properties of the material at the testing temperature. Two citeria, based upon material stability characteristics. arc setup to help classify the cylic load data.
