In this paper, a finite element modeling via ABAQUS/Explicit simulation on a novel fabrication miniature composite fuselage structure is presented. The fuselage structure is modeled as a continuum composite layup that consisted of a woven C-glass fiber/epoxy 200 g/m 2 composite laminated [908] with the orthotropic elastic material properties and adhesively bonded butt joint. The adhesively bond...

This effort explores the evolution and characterization of structural cracks in aircraft fuselage structures in which the loads are varying. During flight, an aircraft fuselage skin and structure are subjected to varied cyclic loads, which can cause embedded cracks and other damage features to change their characteristics due to loading effects. The current research uses finite element modeling...

Existing research on the magnetic coupler of unmanned aerial vehicle (UAV) wireless charging systems usually ignores UAV fuselage, but fuselage causes eddy current loss and reduces a system’s efficiency. Therefore, aiming at above problems, this paper proposes design for using nanocrystalline cores to reduce caused by fuselage. First, parameters asymmetric circular coils were designed higher mu...

An extensive experimental database has been assembled from very detailed teardown examinations of fatigue cracks found in rivet holes of fuselage structural components. Based on this experimental database, a comprehensive analysis methodology was developed to predict the onset of widespread fatigue damage in lap joints of fuselage structure. Several computer codes were developed with specialize...
