  1. COMSOL Analysis:End Loaded Cantilever Beams of Various Cross Sections Gregory Hew

  2. Description of System • End loaded steel cantilever beam • Analyzed at 4 different cross sections • Circular • Triangular • Square • I-Beam

  3. COMSOL Model • Used 3-D Structural Mechanics • Steady State • Boundary Conditions • Edge load • Fixed displacement • Steel Beam • Meshing • Physics Controlled

  4. Results Square Triangular Circular I-Beam

  5. Verification of Results • Analytical solution exists • Based off stress/strain theory. • Utilized to determine the integrity of solution • Error percentage ranged from 0.58% to 1.68%

  6. Comparison of COMSOL and Analytical Solutions

  7. Verified convergence of solutions Slight divergence at extremely fine for circular cross section May be due to difficulties using tetrahedral meshes on circular geometry Mesh Extension
