Buckling Analysis of a Thin-Walled Structure Using Finite Element Method and Design of Experiments

In structural engineering, thin-walled structures play an important role in the design of lightweight model. It carries different loading conditions when it exists any model, and is designed with thin plates or shells. Penetrating kinds holes can decrease their weight facilitate repair maintenance operations, such as those carried out for wing airplane. applications, cutouts are often employed part composite plates. Therefore, this paper attempted to analyse structure a C-cross-section shape. To model structures, finite element method was utilized using ABAQUS commercial tool, results critical buckling load laminate types were obtained. Composite materials have parameters that vary analysis; therefore, optimize current mode experiments used via MINITAB 20 Design-Expert 13 tools. The selected work opening ratio, spacing shape hole output response out. Based on simulation optimization, found will impact response, study investigated optimum best possible outcome analysis.
