3D FEA Analysis of Beam Bracket in ANSYS

Project Overview

This project involves performing Finite Element Analysis (FEA) on a beam bracket using ANSYS, comparing tetrahedral and hexahedral meshing approaches to evaluate structural performance under loading conditions.

Project Highlights

• Equivalent (von-Mises) Stress Analysis:

  • Examined stress distribution across the beam bracket to identify critical failure zones.

• Mesh Comparison:

  • Tetrahedral Mesh: Provided finer meshing in complex regions, but with higher computational cost.
  • Hexahedral Mesh: Achieved better element quality and stress accuracy with lower computational effort.

• Stress Concentration Points:

  • Maximum stress regions identified at the bracket's top surface due to applied loads.
  • Minimum stress points observed near the fixed support.

• Result Interpretation:

  • Tetrahedral Mesh Maximum Stress: 83.9 MPa

  • Hexahedral Mesh Maximum Stress: 89.8 MPa

  • Hexahedral elements provided smoother stress distribution and improved convergence.
