我们考虑了各种设置涉及链与一个或多个缺陷源于节点轴承内部谐振器的引入。在木堆弹性晶格与一个或两个缺陷的实验结果的动机，我们考虑了各种不同的理论方案。这些包括多缺陷链及其传输，反射，特别是捕获能量的能力。此外，它们涉及在空间上分离的缺陷，并且静态地或更有效地动态地使得能够在分离的缺陷之间限制能量。只要有可能，比较的实验与数值模拟，以及与理论的直觉，也提供了一个理由所观察到的结果。
We consider a variety of settings involving chains with one or more defects stemming from the introduction of nodes bearing internal resonators. Motivated by experimental results in woodpile elastic lattices with one or two defects, we consider a variety of different theoretical scenarios. These include multidefect chains and their ability to transmit, reflect, and especially trap energy. Moreover, they involve defects which are spatially separated and either statically or, more effectively, dynamically enable the confinement of energy between the separated defects. Wherever possible, comparisons of the experiments with numerical simulations as well as with theoretical intuition are also offered, to provide a justification for the observed findings.
