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.
将一根长金属丝强行填入二维腔体中会导致形成破碎结构，其中包含一系列具有不同曲率半径的分层级联环。我们通过实验和高分辨率数字技术研究了此类系统中存储的弹性能量分布。结果发现，曲率弹性能量集中的集合的维度为D(S)=1.0±0.1，而质量分布的集合的维度为D = 1.9±0.1。
