Creep Failure and Pyrolysis Damage Mechanism of CFRP Under Thermo‐Mechanical Coupling

ABSTRACT A key challenge in airworthiness of composite aircraft is understanding the thermo‐mechanical response and failure of carbon fiber reinforced polymer (CFRP) in in‐flight fire. A sequentially coupled thermal‐stress analysis with a three‐dimensional thermal response model...

Experimental investigation of the direct shear strength parameters of compacted snow

Abstract. Compacted snow is utilized as a building material in various construction and engineering applications across global high-latitude regions. For the safety assessment of snow and ice structures in cold regions, cohesion and internal friction angle are key shear strength...

Damage Quantification Monitoring of CFRP Structures Cross-Area Based on Transfer Learning

Given the widespread application of carbon fiber reinforced polymer (CFRP) structures in aerospace and automotive manufacturing, the critical role of structural health monitoring (SHM) is increasingly evident. Traditional damage quantification methods exhibit poor transferability...

Numerical Investigation of Aeropropulsive Coupling Effects of Distributed Propulsion Systems under Near-Stall Conditions

Abstract Distributed propulsion (DP) systems offer increased lift, decreased drag, higher propulsion efficiency, and reduced fuel consumption. However, complex aeropropulsive interactions can significantly affect the aerodynamic performance of distributed propulsion systems, part...

Uncertainty-Aware Vision-Based Landing-Site Perception for Autonomous UAV Landing in Urban Environments

Autonomous UAV landing in urban scenes requires a perception module that can identify candidate landing surfaces, reject structural and dynamic hazards, and express uncertainty before a downstream controller commits to a landing maneuver. This study reformulates UAV landing perce...
