We consider sinusoidal undulations which appear on certain garden hoses under normal use. We propose a model, using linear elasticity, explaining this phenomenon, and make a connection with biological structures as well as self-buckling. We compare observations with model predictions and suggest potential applications in the area of shape-changing materials.

不是花园软管不稳定：在弯曲的花园软管中选择波长

我们考虑在正常使用情况下某些花园水管上出现的正弦波状起伏。我们提出一个模型，利用线性弹性来解释这种现象，并与生物结构以及自屈曲联系起来。我们将观测值与模型预测值进行比较，并建议在可变形材料领域中的潜在应用。
