Microhardness of Mollusc Seashell Structures

An inspiration for a new development or improvement of properties of the structural biomimetic materials can be found in nature. Nano- and micro indentation gives valuable information about mechanical response, particularly under compression, but also under tensile and shear loading. The Vickers microhardness of Pinna pectinata (Pinnidae) Adriatic Sea mollusc shell structure has been determined as a function of the indentation load. Particularly, the influence of loading direction on the hardness of the nacreous and prismatic structures has been investigated. The results show that the measured microhardness depends on the load for the nacreous and prismatic structures, except for the prismatic indented perpendicular to the outer surface. The load dependence of microhardness is analysed by the known Meyer’s law, wherefrom the calculated regression coefficients are very high for the all investigated cases.
