The results of creep-buckling experiments on long, simply-supported plates of aluminum alloy 2024-0 at 500 F under axial compression were correlated with a previously developed theory for perfect plates. Corn- pressive-creep properties of the test material were obtained to develop the theoretical results. The plate experiments were performed using a square-tube configuration after an evaluation program indicated that the conventional vee groove-knife edge arrangement for simulating simple support was unsatisfactory for use at elevated temperatures. The theory was found to have predictive value for plate creep buckling when used in normalized form. A simplified approach for predicting creep crippling was also correlated with the test data.
