This study explores the geometric and material behaviors of a gutter bracket under linear and nonlinear conditions using Finite Element Analysis (FEA) with Siemens NX solvers SOL101, SOL106, and SOL401. Polyvinyl Chloride (PVC) was selected for its favorable mechanical properties and corrosion resistance. The study investigates deformation, stress, and displacement of the bracket under a 100 N load, comparing the accuracy of linear and nonlinear analyses. Results indicate that while linear analysis provides a simplified model, nonlinear analysis captures material nonlinearity, geometric rigidity changes, and cyclic loading effects, offering more realistic insights. The findings emphasize the importance of nonlinear solvers in predicting structural behavior under significant deformations, ensuring design reliability and performance optimization in engineering applications.
