华纳和亚当斯开发的新古典弹性体模型预测了一类“软”（零能量）变形。我们发现并描述了全套条带域（层压结构，其中层压板在两种不同变形之间交替），可以在这些软变形对之间形成。所有条带域分为两类，一类是近晶层在界面处不弯曲，但在这种情况下界面带电，另一类是近晶层弯曲但界面从不带电。条纹变形显着增强了宏观弹性响应的柔软度。
The neoclassical model of(and) elastomers developed by Warner and Adams predicts a class of “soft” (zero energy) deformations. We find and describe the full set of stripe domains—laminate structures in which the laminates alternate between two different deformations—that can form between pairs of these soft deformations. All the stripe domains fall into two classes, one in which the smectic layers are not bent at the interfaces, but for which—in thecase—the interfaces are charged, and one in which the smectic layers are bent but the interfaces are never charged. Striped deformations significantly enhance the softness of the macroscopic elastic response.
