在过去的二十年里，圆柱壳的屈曲分析取得了重大进展。欧洲规范现在规定了r/t = 5000以下的坦克的规则。然而，由于过去只有很少的文献可供使用，特别是在r/t = 1500和r/t = 10000之间的非常薄的壁壳，规范规定要么是相当保守的，要么在r/t > 5000的情况下几乎不存在。采用现代施工方法，可以建造出接近完美的薄壁壳体，而这些壳体超出了设计规范的范围。因此，为了实现更经济的设计和更好的可持续性，必须使用复杂的设计工具。
Major advances in the buckling analysis of cylindrical shells have been achieved in the last two decades. Eurocode nowadays provides rules for tanks up to r/t = 5000. However, since only few literature has become available in the past, dealing specifically with very thin walled shells in the range between r/t = 1500 and r/t = 10000, code provisions either are quite conservative or, in case of r/t > 5000, do barely exist. Employing modern construction methods, close‐to perfect, very thin‐walled shells can be built that are out of the scope of the design codes. Therefore, to achieve more economical designs and a better sustainability, sophisticated design tools have to be used.
