The toucan beak: Structure and mechanical response
TLDR
In this article, the structure and mechanical response of a Toco toucan (Ramphastos toco) beak were established, and the beak was found to be a sandwich composite with an exterior of keratin scales (50 Am diameter and 1 Am thickness) and a core composed of fibrous network of closed-cells made of collagen.About:

Biological materials: Functional adaptations and bioinspired designs
TL;DR: In this paper, the authors conduct an analysis connecting the structure (nano, micro, meso, and macro) to the mechanical properties important for a specific function, and address how biological systems respond and adapt to external mechanical stimuli.

Keratin: Structure, mechanical properties, occurrence in biological organisms, and efforts at bioinspiration
TL;DR: Keratin can be classified as α- and β-types as discussed by the authors, and α-types have a characteristic filament-matrix structure: 7nm diameter intermediate filaments for α-keratin, and 3nm diameter filament for β-kkeratin.

Structure and mechanical properties of crab exoskeletons.
TL;DR: The structure and mechanical properties of the exoskeleton (cuticle) of the sheep crab (Loxorhynchus grandis) were investigated and it was found that the exocuticle (outer layer) is two times harder than the endocuticles (inner layer).

Cellular Solids: Structure and Properties
Lorna J. Gibson,Michael F. Ashby +1 more
TL;DR: The linear elasticity of anisotropic cellular solids is studied in this article. But the authors focus on the design of sandwich panels with foam cores and do not consider the properties of the materials.
Journal ArticleDOI
Mechanical properties and the hierarchical structure of bone
TL;DR: Further investigations of mechanical properties at the "materials level", in addition to the studies at the 'structural level' are needed to fill the gap in present knowledge and to achieve a complete understanding of the mechanical properties of bone.

Growth and structure in abalone shell
Albert Lin,Marc A. Meyers +1 more
TL;DR: In this paper, the growth and self-assembly of aragonitic calcium carbonate found in the shell of abalone (Haliotis) is described through a close examination of laboratory-grown flat pearl samples and cross-sectional slices of the nacreous shell.

Comparison of nano-indentation hardness to microhardness
TL;DR: In this article, the authors measured the nano-indentation hardness and micro-hardness in a wide load range (0.1-19600 mN) for five materials.
