Bouligand, Twisted Fibrous Arrangements In Biological-Materials and Cholesteric Mesophases, Tissue Cell, 1972, 4, 189190, DOI:.1016/s0040-8166(72)80042-9.
This allows covalent chains to unfold and provide substantial deformation without disrupting the chain.A sketch of the periodic arrangement of mineralized scales anchored in the demis is shown in Fig.Thanks for your understanding.For this to occur the intertesseral joints must be much narrower than being taller, a condition suggested by a previous morphological study.

However, these materials share a similar layered structural organization.
Many of these strategies hinge on material inhomogeneities, combinations of materials with different properties in arrangements (e.g.
The stress decreases linearly as a function of the total crack length.
When this composite is challenged in tension along the horizontal direction, the deformation will be dominated by the stretching of the interlayer (yellow line in (b).
Finally, the concept of tessellation is generalized to the molecular level, where the coexistence of strong and weak molecular bonds in fibers results in unusual mechanical properties, such as self-healing.All scale bars are.Estrin, Design of responsive materials using topologically interlocked elements, Smart Mater.Materials of this type are very common in nature and include multilayered silica in glass sponges 8,9 ( Fig.Under larger external loads (e.g.
