文摘：通过14B-T6铝合金拉拔方管的局部失稳试验，验证了简支板受压塑性屈曲的各种理论的正确性。所得结果与Stowell的柱、板塑性屈曲统一理论(NACA，TN，No.15456)。除了以前对于柱和法兰所获得的结果之外，这一结果被认为是对基于塑性变形理论的这一理论的令人满意的实验验证。另外两种塑性屈曲理论--变形型和经验割线模量法也与试验结果吻合较好，而流动型塑性屈曲理论与试验结果不一致。
Abstract : An investigation was made to ascertain the validity of various theories for the plastic buckling of compressed simply supported plates by means of local-instability tests of drawn square tubes of l4B-T6 aluminum alloy. The results obtained were in excellent agreement with Stowell's unified theory for the plastic buckling of columns and plates (NACA TN No. l5456). This agreement, in addition to that previously obtained for columns and flanges, is considered a satisfactory experimental verification of this theory which is based on a deformation theory of plasticity. Two other plastic buckling theories of the deformation type and the empirical secant-modulus method also gave a close correlation with the test results, but a plastic buckling theory of the flow type showed a lack of agreement.
