将一根长金属丝注入二维腔体的强制填料会导致包含不同曲率半径的分层级联环的破碎结构。我们从实验和高分辨率数字技术研究了存储在这种系统中的弹性能量的分布。结果表明，曲率弹性能集中的集合维数D(S) = 1.0 +/- 0.1，质量分布的集合维数D = 1.9 +/- 0.1。
Forced packing of a long metallic wire injected into a two-dimensional cavity leads to crushed structures involving a hierarchical cascade of loops with varying curvature radii. We study the distribution of elastic energy stored in such systems from experiments, and high-resolution digital techniques. It is found that the set where the elastic energy of curvature is concentrated has dimension D(S) = 1.0 +/- 0.1, while the set where the mass is distributed has dimension D = 1.9 +/- 0.1.
