Load and temperature influence on a GW-SHM system for a composite fuselage

Year: 2025

Type: conference-paper

Abstract: . A full-scale composite door surrounding aircraft structure was instrumented with a GW-SHM system and subjected to three representative quasi-static load cases using a hydraulic test rig. The test was performed in a hangar under uncontrolled temperature environment, resulting in broad temperature variations throughout the experiment. This work focuses on differentiating between benign environmental and operational conditions and barely visible impact damage. A data-driven approach based on Gaussian Processes is used to detect barely visible impact damage introduced during the test campaign, differentiating between benign environmental/operational conditions and barely visible impact damage.
