Abstract:

The present study is an experimental investigation of the creep buckling behavior of simply supported flat rectangular plates. The plates are modeled in the experiments by the four faces of square prisms which are submitted to pure axial compression in a special oven at a temperature of 600F. Thirty-three square prisms built of 0.020 in. thick 2024-T3 aluminum alloy sheet were tested at various stress levels. The continuously recorded end-shortening curves led to the determination of a creep power law for the material at 600F. The ensuing comparison of the buckling time obtained from the experiments with the theory yielded fairly good results even though the experimental scatter-band was quite large. Author
