1. Bonsmann, Jarrod. Finite Element Analysis for Use in Fluid Structure Interaction of a High Aspect Ratio Thin Airfoil using Drop-Plies.

Degree: MS, Mechanical Engineering - Mechanical and Aerospace Engineering, 2010, University of Florida

Abstract of Thesis Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Master of Science FINITE ELEMENT ANALYSIS FOR USE IN FLUID STRUCTURE INTERACTION OF A HIGH ASPECT RATIO THIN AIRFOIL USING DROP-PLIES By Jarrod M Bonsmann May 2010 Chair: Peter Ifju Cochair: Bhavani Sankar Major: Mechanical Engineering One of the primary advantages in using fiber composite materials for mechanical applications is the ability of the user to tailor the mechanical properties of the material to its specific application. One such example is the use of graphite fiber woven cloth embedded in epoxy for the fabrication of high aspect ratio thin airfoils. These airfoils can be used in a number of fields from rotor blade technology to recreational and sporting equipment such as a racing windsurfing fin. This thesis uses a windsurfing fin for design verification. By using graphite/epoxy material one is able to vary the ply lay-up to produce different stiffness properties in the fin as well as different bend twist coupling characteristics in the airfoil. Mechanical tests using electrical resistance strain gages are performed to obtain the various material properties of the graphite/epoxy system used. ABAQUS finite element analysis (FEA) program and MatLab technical computing software are used to create a finite element model for use in analyzing the deformation characteristics of the fin in various loading conditions. The model deformations are verified using Visual Image Correlation (VIC) to study the deflections of a fin with known material lay-up properties and loading conditions. Once all of these tests and studies are performed Athena Vortex Lattice (AVL) program is used to obtain the fluid structure interaction pressure loads on a fin in water. With these loads and the computer model, a tool is developed that can be used to study and optimize the design of the windsurfing fin without the costly (both time and monetary) creation of a plethora of fins utilizing almost endless possibilities of ply lay-up directions and lengths.
