二维皱曲丝的塑性形变
Plastic Deformation of 2D Crumpled Wires
摘要：
当一个单一的长段的弹性线被注入到一个封闭的二维腔通道，形成一个复杂的结构的分层环。在最大堆积密度的限制下，这些结构可以用几个标度律来描述。在本文中，它是研究这种包装过程，但使用塑料丝，使起源完全不可逆的结构不同的形态。特别是，它是实验研究的塑性形变从圆形到扁圆形配置的皱巴巴的电线，通过施加轴向应变。除其他外，它表明，尽管塑性，不可逆性，和非常大的变形，缩放仍然观察到。
英文摘要：
When a single long piece of elastic wire is injected trough channels into a confining two-dimensional cavity, a complex structure of hierarchical loops is formed. In the limit of maximum packing density, these structures are described by several scaling laws. In this paper it is investigated this packing process but using plastic wires which give origin to completely irreversible structures of different morphology. In particular, it is studied experimentally the plastic deformation from circular to oblate configurations of crumpled wires, obtained by the application of an axial strain. Among other things, it is shown that in spite of plasticity, irreversibility, and very large deformations, scaling is still observed.
