讨论了具有拓扑互锁单元结构的异常力学响应。在点荷载作用下，其表现为伪塑性，在部分卸载曲线中具有负刚度。这种效应是结构中固有的，并且归因于由于元件的旋转而改变的接触条件。
Unusual mechanical response of a structure with topologically interlocked elements is discussed. Under point loading, it behaves pseudo-plastically, with a negative stiffness in part of the unloading curve. This effect is inherent in the structure and is attributed to changing contact conditions due to rotation of the elements.
