The rostrum of a Paddlefish is used as an antenna to detect electrostatic impulses emitted by plankton and also for hydrodynamic stability while feeding. The rostrum is formed by a network of cartilage, tissue, and interlocking star shaped bones called stellate bones. The objective of this work is to study the load transfer mechanisms of the rostrum bone structure. Steel with elastic-plastic behavior is considered in this study as a basic homogeneous material to evaluate the performance of four models using the following elements first-order reduced integration, first-order full integration, second-order reduced integration, and second-order full integration. From the study is found that second-order formulation resulted in lower structural stiffness as seen by higher displacements and stresses than using first-order formulated elements. Von Mises stresses as well as global stresses along the rostrum and at a particular location and bones were extracted and compared for the second-order-reduced integration model.
