Abstract
This research project focuses on finite element modeling (FEM) and finite element analysis (FEA), two techniques used in engineering to simulate and analyze complex structures. FEM is a numerical method that divides a large, complicated structure into smaller, simpler pieces called finite elements. These elements are then analyzed individually, and the results are combined to understand the behavior of the entire system. This approach allows engineers to create a digital twin and study a structure’s response to various forces, such as stress, strain, heat, or vibrations, without the need for expensive or time-consuming physical prototypes. The project aims to model a very flexible wing using FEA techniques and commercial software like Nastran or Abaqus. It starts with modeling the wing as a simple 1D structure under basic static loads, such as gravity or concentrated forces. The models then evolve to 2D elements for increased fidelity and refinement, and ultimately to a detailed 3D model, providing a more accurate representation of the actual, as-built wing. Key aspects of this process, including meshing, boundary conditions, and solver settings, will be explored at each stage to ensure accurate simulations. The results are also compared to the experimentally available data, to improve the quality of the model(s). Once the 3D model is developed, it will be used for further evaluation of the wing, including design optimization and aeroelastic modeling. This will simulate virtual wind tunnel testing, which is essential for understanding how the structure interacts with aerodynamic forces.
