Abstract

Pressure vessels are widely used in a broad range of applications targeting different industries. Therefore, they need to be designed carefully to satisfy the specific design requirements related to each application. Failure performance, weight and packing efficiency are important factors that should be considered when designing pressure vessels, and there is a constant need for improving these key factors. An appealing design is a lightweight pressure vessel that contains a large volume and can withstand large values of internal pressure before failure. Bend-free super ellipsoids of revolution, enabled by stiffness tailoring via variable angle tow placement, is an appealing solution that makes them possible candidates for future pressure vessels. To date, the bend-free design methodology for super ellipsoids of revolution has only been developed under uniform internal pressure loading. However, in reality, pressure vessels can also be subjected to thermal loads during service. Therefore, this study develops an initial bend-free design methodology for super ellipsoids of revolution that are subjected to both uniform internal pressure and thermal loads.
