Abstract Optimization means the mathematical determination of the optimal decisions out of diverse alternatives. Based on thepreceding Finite Element Analysis (FEA), a proposed shell produced a maximum stress that exceeded the design value. To makethe design feasible, an optimization was done to minimize the maximum stress by using the gradient method. The performance ofthe structure can be optimized to fulfil the design requirements with the optimum value of displacement to achieve the objectivefunction. The results show that the optimum displacement is 8.8mm, which reduced the maximum stress by 99.94% from theinitial level. Thus, optimization methods are important for new applications of shell structures to find their best parameters in thedesign stage.
