The recently discovered undamped localized mode at the end of an elastic strip is demonstrated to be particularly relevant in the plane stress setting, where it exists for the Poisson ratio 0.29. This paper also emphasizes the difference between low-frequency edge modes, typically characterized by low variation across the plate (or shell) thickness, and high-frequency edge modes, whose natural frequencies are of the order of thickness resonance frequencies.
最近在弹性条带末端发现的无阻尼局域模式被证明在平面应力情况下特别相关，在该情况下，泊松比为0.29时它会存在。本文还强调了低频边缘模式（通常其特征是在板（或壳）厚度上变化较小）与高频边缘模式之间的差异，高频边缘模式的固有频率与厚度共振频率相当。
