Design of filament–wound domes based on continuum theory and non-geodesic roving trajectories

摘要: Abstract In this paper the optimal shapes and fiber architectures of non-geodesics-based domes for pressure vessels are determined upon condition equal shell strains. Based on continuum theory non-geodesic law, system differential equations governing meridian profiles is derived. A specific function chosen to describe slippage coefficient distribution desired path, in order ensure C1 continuity roving paths when passing dome–cylinder conjunction. Next, various material anisotropies; related winding angle developments trajectories also presented. The performance factors obtained using coefficients polar opening radii. results show that structural efficiency dome improves with increasing coefficient. It concluded designed present method gains better than one relying geodesics.
