Project Description

Inverse Finite Element Method Investigation for Adaptive Structures Project
Most Structural health monitoring algorithms do not realistically predict the characteristics of a structure to give a good overall pictures of the health of the system. The purpose of this technology project is to demonstrate and validate the Inverse FEM method on an adaptive compliant trailing edge structure. The inverse problem of real-time reconstruction of full field structural displacements is addressed through the application of a new variation formulation leading to versatile, robust and computationally efficient inverse shell finite element analysis. Utilizing surface strain measurements from strain sensors mounted on the load-carrying structural components, the methodology enables accurate computations of the three-dimensional displacement field. This high fidelity computational technology is essential for providing feedback to the actuation and control systems of the next generation of aerospace vehicles. More »
