The finite element analysis was verified by experimental data obtained from the literatures. The calculations analyzed various factors influencing the shear buckling of aluminum plates such as the width-to-thickness ratio, stiffener spacing, alloy temper, and end post.
利用已有试验结果验证了有限元模型;研究了影响铝板剪切屈曲的各种因素:腹板宽厚比、加劲肋间距、材料热处理类型、梁端是否有封头肋板;并给出了铝板剪切屈曲的临界屈曲强度和屈曲后强度的计算方法。
