Inhaltsangabe:
- <p><code>statFEM-Recon</code> is a MATLAB-based implementation of the <strong>Statistical Finite Element Method (statFEM)</strong> designed to address uncertainty quantification (UQ), data assimilation, and model updating for structural mechanics problems. This project focuses on two benchmark cases:</p> <ol> <li><strong>One-Dimensional (1D) Tension Bar under Tip Load:</strong></li> </ol> <ul> <li>Simulates linear material behavior.</li> <li>Linear and nonlinear synthetic experimental data are generated to emulate real-world measurements.</li> <li>Uncertainty is incorporated through both Monte Carlo (MC) simulations and Polynomial Chaos Expansion (PCE).</li> </ul> <ol> <li><strong>Two-Dimensional (2D) Infinite Plate with a Hole:</strong></li> </ol> <ul> <li>Models the plate using both Linear Elastic and St. Venant-Kirchhoff (nonlinear) material models.</li> <li>Synthetic observations are generated using the St. Venant-Kirchhoff model to test model selection and updating.</li> </ul>
