Finite Element Parametric Analysis of Stiffened Plates for Deflection Reduction Using ANSYS APDL
Abstract: This study presents a finite element analysis of stiffened plates subjected to point loads and uniformly distributed loads using ANSYS APDL. A square aluminum plate with fixed boundary conditions is analyzed to evaluate maximum deflection for different stiffener configurations while maintaining constant material volume. Parametric studies are conducted by varying stiffener length, thickness, and height. Different stiffener layouts including single stiffeners, cross stiffeners, and diamond-shaped stiffeners are examined. Results show that the addition of stiffeners significantly reduces plate deflection compared with a bare plate. The optimum configuration is obtained for a stiffener with length 640 mm, height 50 mm, and thickness 10 mm, which produces the minimum deflection under uniform loading conditions. The findings demonstrate that proper stiffener geometry can substantially improve structural rigidity while maintaining material efficiency.
