Locally resonant metamaterials (LRMs) have been extensively investigated for their superior attenuation performance in the band gap frequencies despite not resulting in a large mass increase, comparatively. However, for their application on actual industrial structures, there exist limitations, the most important of which is the flexibility of the LRM structure. Several studies have succeeded in attaching LRMs to curved surfaces, but if the curvature changes, the unit structure must be redesigned. In this paper, a flexible LRM design independent of curvature is proposed, and numerical simulations illustrate the implementation of the band gap in a beam. Proof of concept of the flexible LRM has been shown through modal experiments on various curved surfaces. Excellent attenuation characteristics of the flexible LRM are demonstrated via a comparison with a constrained layer damping treatment, which are typically considered in noise, vibration and harshness (NVH) area. As the proposed flexible LRM can be attached to various curvatures without restriction or redesign, it differentiates itself as a practical alternative to other LRM designs and expected to be explored in diverse applications.

局部共振超材料 (LRM) 因其在带隙频率中的优异衰减性能而被广泛研究，尽管相对而言并没有导致大量的质量增加。然而，对于它们在实际产业结构上的应用，存在局限性，其中最重要的是LRM结构的灵活性。几项研究已经成功地将 LRM 附加到曲面上，但如果曲率发生变化，则必须重新设计单元结构。在本文中，提出了一种独立于曲率的灵活 LRM 设计，并且数值模拟说明了光束中带隙的实现。柔性 LRM 的概念证明已通过各种曲面上的模态实验得到证明。柔性 LRM 的出色衰减特性通过以下方式得到证明一种与通常在噪声、振动和粗糙度 (NVH) 区域中考虑的约束层阻尼处理进行比较。由于所提出的灵活 LRM 可以不受限制或重新设计地连接到各种曲率，因此它作为其他 LRM 设计的实用替代方案脱颖而出，并有望在各种应用中进行探索。
