出于局部性质的弹性不稳定性在径向拉伸薄环形板，我们调查的情况下，当他们的机械性能是分段常数的这种配置的屈曲阻力。通过考虑由两个完全粘结在一起的具有不同线弹性性质的子环形区域组成的板，当径向恒定位移场施加在板的内边缘和外边缘上时，对应于该情况的中性稳定性包络线被数值地研究得相当详细。这些结果是补充的渐近减少策略，提供了一个大大简化的特征值问题，能够描述原来的屈曲问题的限制非常薄的板。
Motivated by the localized nature of elastic instabilities in radially stretched thin annular plates, we investigate the resistance to buckling of such configurations in the case when their mechanical properties are piecewise constant. By considering a plate consisting of two sub-annular regions perfectly bonded together and with different linear elastic properties, the neutral stability envelope corresponding to the case when radial constant displacement fields are applied on the inner and outer edges of the plate is investigated numerically in considerable detail. These results are complemented by an asymptotic reduction strategy that provides a greatly simplified eigenproblem capable of describing the original buckling problem in the limit of very thin plates.
