发展了膜双层的纯弯曲，包括每个膜半层的不同性质。连接的和未连接的双层表面都会被处理。双层弯曲阻力是平行表面压缩“阻力”的结果。中性面是上、下表面压缩系数的函数，不一定与中面重合。界面化学自由能密度(表面张力)的变化会产生诱导弯矩并产生曲率；即使是很小的变化也会产生明显的曲率效应。化学诱导的瞬间被认为是红细胞皱缩的一种可能机制。
Pure bending of a membrane bilayer is developed including different properties for each membrane half. Both connected and unconnected bilayer surfaces are treated. The bilayer bending resistance is the resultant of parallel surface compression "resistances." The neutral surface is a function of the upper and lower surface compressibility moduli and does not necessarily coincide with the mid-surface. Alterations in the interfacial chemical free energy density (surface tension) on either face can create induced bending moments and produce curvature; even small changes can have a pronounced curvature effect. Chemically induced moments are considered as a possible mechanism for crenation of red blood cells.
