本文用直接法得到了多层内屈曲的近似理论，并推广到非正弦变形。数值讨论包括不等厚的主管和无能层的情况。简单的表达式推导出的刚性约束或自约束显示间隙流的影响的主波长。该理论是在粘性介质中使用固体和流体力学的背景下，是有效的大压缩应变和适度的斜坡。它的适用性，弹性和粘弹性介质。
The approximate theory of internal buckling of multilayers is obtained by a direct method and generalized to nonsinusoidal deformations. The numerical discussion includes the case of unequal thickness of competent and incompetent layers. Simple expressions are derived for the dominant wave length for rigid confinement or self-confinement showing the influence of interstitial flow. The theory is presented in the context of viscous media using both solid and fluid mechanics and is valid for large compressive strain and moderate slopes. Its applicability to elastic and viscoelastic media is indicated.
