INTRODUCTION/BACKGROUND
• Angle bar is used extensively as a building material
to route cable from one point to another
• Goal of project is to compare the effects that the
material has on the strength performance of angle
bars
PROBLEM DESCRIPTION
• Model an angle bar in Abaqus/CAE
• Modify models with different physical properties
such as material, mass and size
• Compare the analytical results of the performance
of the angle bar to experimental data
APPROACH/METHODOLOGY
• Create three-dimensional model of a angle bar
including modeling composite material using
Abaqus/CAE
• Run and repeat analysis with both coarser and finer
meshes to determine the adequacy of the mesh
• Re-run analysis using different angle bar physical
properties
ANGLE BAR GEOMETRIES
• 2” x 2” x ¼” Angle Bar created
