composite geodesic high rise

Design and Optimization of Filament Wound Composite Pressure ...Simulations of geodesic and non-geodesic trajectories are performed for winding toroidal pressure vessels. Last but not least, since ultra-high pressure vessels require thick-walled designs, this dissertation is also extended to three-dimensional problems where the through-thickness stress gradient is taken into account. A three-dimensional (3D) elasticity analysis on multi-layered thick-walled pressure vessels is here addressed. In order to better understand the design approaches of ...
