Nacre (mother-of-pearl) from mollusc shells is a biologically formed lamellar ceramic. The inelastic deformation of this material has been experimentally examined, with a focus on understanding the underlying mechanisms. Slip along the lamellae tablet interface has been ascertained by testing in compression with the boundaries oriented at 45° to the loading axis. The steady-state shear resistance tss has been determined and inelastic strain shown to be as high as 8%. The inelastic deformation… 
An Experimental Investigation of Deformation and Fracture of Nacre–Mother of Pearl
Nacre, also known as mother-of-pearl, is a hard biological composite found in the inside layer of many shells such as oyster or abalone. It is composed of microscopic ceramic tablets arranged in
Mechanical properties of nacre constituents and their impact on mechanical performance
The mechanical properties of nacre constituents from red abalone were investigated. Electron microscopy studies revealed that the tablets are composed of single-crystal aragonite with nanograin
Micromechanics of fracture in nacre from mollusk shells
Nacre is the iridescent layer found inside many mollusk shells. This natural composite is mostly made of microscopic ceramic tablets bonded by a small fraction of organic materials. Nacre is 3,000
Micromechanics and Macromechanics of the Tensile Deformation of Nacre
This paper investigated the mechanics of nacre using a micromechanical representative volume element model, where the protein-rich organic matrix is modeled by a recently developed finite deformation

Micromechanics of engineered interphases in nacre-like composite structures
Abstract Although the composition of polymer matrix is only 5% by weight, the presence of polymer as an interlayer between the brittle aragonite bricks significantly enhances the toughness


Observations of damage morphologies in nacre during deformation and fracture
The deformation, fracture and toughening mechanisms of nacre from a kind of fresh-water bivalve mollusc (Cristaria plicata) were studied by SEM, TEM and microindentation tests. Experimental results
The mechanical design of nacre
Mother-of-pearl (nacre) is a platelet-reinforced composite, highly filled with calcium carbonate (aragonite). The Young modulus, determined from beams of a span-to-depth ratio of no less than 15 (a

Mother of pearl, or nacre, is one of a number of characteristic skeletal structures of molluscs, occurring in cephalopods, gastropods and bivalves. It consists of plates of aragonite, about 0.3 μm
Molecular mechanistic origin of the toughness of natural adhesives, fibres and composites
Natural materials are renowned for their strength and toughness,,,,. Spider dragline silk has a breakage energy per unit weight two orders of magnitude greater than high tensile steel,, and is
Transformation Plasticity of CeO2‐Stabilized Tetragonal Zirconia Polycrystals: I, Stress Assistance and Autocatalysis
Transformation plasticity in CeO2-stabilized tetragonal zirconia polycrystals due to the tetragonal-to-monoclinic transformation was studied by inducing volumetric and shear deformation under
Mechanics of Transformation‐Toughening in Brittle Materials
Particles which undergo a stress-induced martensitic transformation are known to toughen certain brittle materials. The enhanced toughness can be considered to originate from the residual strain
