Applied Sciences, Vol. 16, Pages 8970: Ground Calibration and Airborne Physical-Consistency Assessment of Composite-Wing Sectional Loads Using Fiber Bragg Grating Sensors

3+ day, 45+ min ago   (349+ words) This study develops a fiber Bragg grating (FBG)-based method for identifying sectional loads on a full-scale RX1E-A composite aircraft wing. Thirty-two load-sensitive FBGs were installed at four spanwise sections. Multi-case ground loading with different spanwise distributions and chordwise positions…...

Applied Sciences, Vol. 16, Pages 8371: A Study on Hybrid Straightening Strategies for High-Speed Linear Guides with Hardened Layers Based on Inverse Finite Element Modeling

3+ week, 19+ hour ago   (545+ words) High-frequency induction hardening enhances the surface wear resistance and contact fatigue life of high-speed linear guides, but simultaneously produces an inhomogeneous, layered cross-sectional structure comprising a high-strength, low-ductility outer hardened layer and a low-strength, high-ductility inner core. This structural heterogeneity…...

Applied Sciences, Vol. 16, Pages 8215: A Fail-Safe Topology Optimization Method for Fiber-Reinforced Composite Structures Under Dynamic Loads

3+ week, 4+ day ago   (533+ words) A fail-safe topology optimization method for fiber-reinforced composite structures under dynamic loads is proposed to achieve the concurrent optimization of structural topology and fiber orientations, as well as enhance the structural redundancy subject to damage cracks of fiber-reinforced composite structures…...
