Multifunctional Composite Structures
Abstract
In this project, computational tools were developed that help in designing and analyzing multi-functional composite structures that have sensing and actuation capabilities. Magnetic actuation of composite structures using built-in or embedded electromagnetic devices was studied. The main application of interest is micro air vehicle wings that are designed to flap to generate thrust and lift. Computational tools were developed to design and analyze such structures actuated by magnetic forces. Coupled magnetostatic-elastostatic analysis capability was implemented into a pre-existing software (named IBFEM) developed at the University of Florida that can perform finite element analysis without the need for generating mesh. After a systematic comparison of several actuator designs, it was concluded that a coil actuator built into composite structures is an ideal means for actuation of composite structures. A conceptual design of a flapping wing vehicle was developed. A method for sensing load application and damage in composite structures by determining change in resistivity/conductivity was also studied. An algorithm for solving inverse problem to determine average resistivity values in composite structures was demonstrated.
