In this study we have presented measurements and calculations to characterize mineralized, radular teeth in several species of mollusc species. Properties examined include (1) distribution of hardness and elasticity, (2) internal structure, (3) patterns of wear, (4) shape, and (5) positioning during feeding. A finite element analysis was performed to study the distribution of stresses in the tooth generated during feeding. Two-dimensional models were used differing in shape, feeding position and elasticity distribution. In the following we will discuss the results in terms of the functionality of the properties studied. Finally, ideas will be expressed as to the implementation of some of our findings into an industrial design.
