Abstract

The pressure vessel is a closed container designed to hold the fluid in a pressure different from the atmosphere (atmospheric) pressure, which is usually cylindrical or spherical to hold or perform chemical processes of liquids or gases.This experiments is done to optimize the under pressure cylinders. In this thesis the cylinders will be mass optimized and constructed using composite sustenance. The optimization and design is on the basis of figures and final elements analysis. According to this method, first the under pressure cylinders with a thin steel wall and then the under pressure cylinders with composite body are modeled by ABAQUS. Then the exterior and axial tensions tolerable by fibers as well as failure criterion are studied by the software after that, the results will be compared and analyzed by the MATLAB codes. Finally after studying the direction and the ideal angle of fibers curvature in order to get the least weight and the highest tension resistance, the best angle will be chosen and the results will be analyzed by the ABAQUS
