Overview
Performed a finite element analysis (FEA) study on a steel angle bracket subjected to a specified load condition. The analysis determined the von Mises stress distribution, maximum deflection, and factor of safety across the geometry.
Methodology
- Geometry modeling — The steel angle section was modeled in SolidWorks with precise cross-sectional dimensions and length.
- Material definition — AISI 1020 steel properties (Young's modulus, Poisson's ratio, yield strength) applied.
- Boundary conditions — Fixed constraint at the mounting face; point load applied at the free end.
- Mesh generation — Curvature-based mesh with mesh refinement at stress concentration regions (fillets, corners).
- Simulation — Static structural analysis run in SolidWorks Simulation.
Results
The FEA output identified the critical stress concentration at the inner radius of the angle section. The maximum von Mises stress was compared against the material yield strength to confirm an adequate factor of safety. Displacement results confirmed the structure remained within acceptable deflection limits under the applied load.
Key Takeaways
This analysis reinforced the importance of stress concentration factors at geometric discontinuities and demonstrated how FEA can complement hand calculations to validate or refine a structural design before fabrication.
