马蹄墙具有独特的层次结构，使其能够在高冲击场景中生存下来。以前的作者已经探讨了压缩，粘弹性和断裂控制性能的蹄壁，并建议，这种复杂的结构起着至关重要的作用，蹄的行为。然而，结构和蹄墙行为之间的联系主要是使用断裂后分析。在这里，定期微计算机断层扫描被用来观察压缩，断裂和放松过程中的蹄的细观和微观结构的时间行为。这些结果揭示了蹄壁的结构各向异性及其中空小管在不同方向、不同水合水平和蹄壁内不同位置压缩时的行为。本文还首次报道了压缩过程中小管桥的行为。这项研究阐明了几种断裂现象，包括裂纹的方式在小管接口和小管桥接，小管逮捕，和纤维桥接偏转。最后，松弛试验用于显示小管腔如何在压缩后恢复其形状。
The equine hoof wall has a unique hierarchical structure that allows it to survive high‐impact scenarios. Previous authors have explored the compressive, viscoelastic, and fracture control properties of the hoof wall and suggested that this complex structure plays a vital role in the hoof's behavior. However, the link between the structure and the behavior of the hoof wall has been made primarily with the use of post‐fracture analysis. Here, periodic microcomputed tomography scans are used to observe the temporal behavior of the hoof's meso and microstructures during compression, fracture, and relaxation. These results shed light on the structural anisotropy of the hoof wall and how its hollow tubules behave when compressed in different directions, at different hydration levels, and in various locations within the hoof wall. The behavior of tubule bridges during compression is also reported for the first time. This study elucidates several fracture phenomena, including the way cracks are deflected at tubule interfaces and tubule bridging, tubule arresting, and fiber bridging. Finally, relaxation tests are used to show how the tubule cavities can regain their shape after compression.
