Design Optimization of A Sandwich Pressurized Shell

Abstract - An open-ended horizontal circular sandwich pressurized shell, constrained at both ends, is loaded by internal uniform pressure. During the optimization process of the sandwich pressurized shell, the proper choice of the geometrical constraints, by ensuring that a minimum weight may make a problem. The objective function of the weight per unit length of the corrugated (trapezoidal) core sandwich pressurized shell is solved as the optimization problem. The structure Optimization is subjected to constraints of the stress. In this paper, the optimal design variables of a series of a sandwich pressurized shell of given loads have been defined and validated by the finite element. The design optimization results are presented in diagrams form. Keywords - Pressurized Sandwich Cylinders, Corrugated Core Sandwich Panels, Fem; Structural Optimization, Optimal Design.
