Optimal Design of the Composite Laminate Vessel Based on SCGM

The purpose of this study is to optimize the design of the composite laminate vessel for minimizing the stress concentration. The optimum design of this study uses the finite element method combined with the simplified conjugated gradient method (SCGM) to find the minimization of Von Mises stress of the vessel. In this study, the composite laminate vessel with the aluminum liner and the carbon fiber/epoxy layer are considered. The winding angle and the thickness of composite layer are proposed as the optimal design variables. Through this optimization, the best combination of the thickness and the winding angle of composite layer can be obtained to reach the minimum stress concentration.
