Dentin and enamel are viewed here as multi-scale composites comprising a staggered micro-structure made of stiff platelets embedded in a more compliant matrix, and further assembled into macroscopic composite-like structures. Mechanical models are formulated for both tissues and their effective moduli are evaluated analytically. The resulting predictions are in very good agreement with Finite Elements (FE) simulations and experimental data from the literature. The models developed in this study demonstrate the possibility, in certain cases, to generate special mechanical effects linked to the structural complexity of these tissues.
牙本质和牙釉质被视为多尺度复合材料，由交错的微结构组成，该微结构由嵌入在较软基质中的硬小板组成，并进一步组装成宏观复合材料样结构。为这两种组织建立了力学模型，并对其有效模量进行了分析评估。所得预测与有限元（FE）模拟和文献中的实验数据非常吻合。本研究中开发的模型表明，在某些情况下，有可能产生与这些组织的结构复杂性相关的特殊力学效应。
