Fracture mechanism of nacre in shell was investigated. The main interest was focused on the role of the organic phase. From evaluation of mechanical properties and observation of microscopic fracture behavior, it was revealed that the sliding behavior at the interface between aragonite plates in nacre was controlled by the organic phase and thereby the excellent mechanical properties were achieved. This behavior was quantitatively understood using a model, which helps obtain a design principle for ceramics composites.

研究了贝壳珍珠层的断裂机理。主要兴趣集中在有机相的作用。通过力学性能的评价和微观断裂行为的观察，揭示了珍珠质文石板之间界面的滑动行为是由有机相控制的，从而获得了优异的力学性能。使用模型可以定量地理解这种行为，这有助于获得陶瓷复合材料的设计原理。
