Bone and nacre are prime examples of natural composites with high strength and toughness. Previous studies on mechanical performance of these materials show that their outstanding properties are direct results of the nano-scale features and the optimized arrangement of the elements. To provide the outstanding mechanical functions, nature has evolved functionally graded interfaces. Particularly in nacre, organic-inorganic interface in which the proteins behave stiffer and stronger in proximity of calcium carbonate minerals provide an impressive role in its structural integrity and mechanical deformation. However, further research on the role of the interface properties as a guide on design and synthesize new materials is essential. In this study, a micromechanical analysis of the mechanical response of “Brick-Mortar” and “Brick-Bridge-Mortar” composites is presented considering interface properties. The closed-form solutions for the displacements in the elastic components as a function of constituent properties can be used to calculate the effective mechanical properties.
