Burst Strength Analysis of Composite Pressure Vessel using Finite Element Method

Currently, composite pressure vessels are widely utilized in industries like the oil and gas industry and etc. The demand for such vessels is constantly increasing due to their better strength properties than conventional metallic pressure vessels which are heavy and highly prone to corrosion. Thus, this prompts for a more cost effective and sustainable method to assess structural integrity of a composite pressure vessel which could minimize burst failures during operations. However, the main problems are the lack of literatures and research works for design optimization as well as the lack of defined materials for composite pressure vessel construction. Hence, the main objectives of this project are to perform burst failure analysis and to conduct parametric burst failure studies on composite pressure vessels using finite element method. The main scopes of this project are the adaptation of failure criteria like Tsai-Wu, Tsai-Hill and maximum stress in performing burst failure analysis as well as parametric studies on the optimal filament orientation angle and materials used for the liner and shell of a composite pressure vessel
