Optimization of material and stacking sequence of laminated composite for use in oil/gas pipes and pressure vessels

Project: Research

Project Details


Recently developed structural materials with targeted mechanical properties can best be combined with the utilization of the available computational tools to end up with an optimum design. Due to their excellent mechanical characteristics like high strength and stiffness to weight ratios and high chemical resistance, laminated composite materials have been becoming increasingly popular in different industrial applications. While the application of these materials has been dominated by the aerospace industry in the past decades, their application to oil and gas industry is relatively new and lacks test data and understanding of structural behaviour under various mechanical and thermal loads. Thus, the main concentration of this project is to study, theoretically and numerically, the structural behaviour of laminated composite pipes and pressure vessels used in the oil and gas industry. The project aims to achieve an optimum design of laminated composite pipes and pressure vessels. The optimization involves the material selection (fiber and matrix), the winding angles of fibers and the thickness breakup of layers. The theoretical formulation and analysis will be performed by utilizing the computational capabilities of the Wolfram Mathematica software while the numerical analysis will be carried out using COMSOL Multiphysics software. The outcomes of the project will be formulated in terms of design guidelines in the form of closed-form formulas and design table/charts
