The proposed research investigates the unique structure of the rostrum of the paddlefish (Polyodon spathula) for use in bio-inspiration. The rostrum comprises three different materials: midline cartilage, a network cartilage structure, and matrix tissue. The structure-property relationships of these materials were studied with various mechanical testing and imaging techniques. The mechanical properties and stress-strain behavior were applied to a material model that characterizes each material. A three-dimensional model was constructed from computed tomography images, and a mesh was exported for use in finite element simulations. Different boundary conditions were applied to show how the rostrum responds under deformation giving a stress distribution arising from different loadings. Finally, a new robust design paradigm is introduced with bio-inspiration introducing constraints and is explained through using the paddlefish rostrum as an example of a cell tower or antenna.
