Multiscale mechanics and optimization of gastropod shells

TL;DR: The mechanical properties and fracture characteristics of nacre and their dependences on the structural orientation and hydration state were elucidated in terms of mechanics behind failure and quantitative relationships were established between the Mechanical properties and off-axis angle based on different failure criteria.

TL;DR: In this article , the authors examined the fabrication of two nacre structures, a nacre columnar (NC) and an nacre sheet (NS), and explored their mechanically superior stacking structure, mechanism of failure, crack propagation, and energy dissipation.

TL;DR: In this paper, a rhombohedral CaCO3 with a specific lamellar texture was obtained by employing sticky rice polysaccharide as an additive in the growth medium.

TL;DR: Due to the low shear strength of deep-sea sediment, crawled mineral collector is easily slips in the deep sea mining process, therefore, high-traction bionic grouser is needed to be studied to impr...

TL;DR: In this paper, the second-rank tensors of a tensor were modeled as tensors and they were used to model the deformation of polycrystalline materials and their properties.

TL;DR: In this paper, an overview of mechanical behavior is presented, including Elastic Behavior, Dislocations, Plastic Deformation in Single and Polycrystalline Materials, Strengthening of Crystalline materials, Composite Materials, Fracture Mechanics, Toughening Mechanisms and the Physics of Fracture.

TL;DR: The tensile strength of mother-of-pearl (nacre) is of the order of 170 MPa (dry) and 140 MPa(wet), values which are best modelled assuming that pullout of the platelets is the main mode of failure as discussed by the authors.

TL;DR: In this article, the structure of nacre is described over several length scales and the tablets were found to have wavy surfaces, which were observed and quantified using various experimental techniques.
