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
ANGLE BAR GEOMETRIES
• Thickness (t) is 0.25”

LOADS
• A pressure load of 9 psi is applied to the top surface
BOUNDARY CONDITIONS
• All degrees of freedom (DOFs) are constrained on
the back side of the angle bar to prevent
movement and rotation in all directions
MESH
• Element used is the S4R
• 4-noded doubly curved shell element
MILESTONE/DEADLINE LIST
• Milestones
• Research experimental data on composite and steel
performances
• Research material properties for composite and steel angle
bars
• Create FEM of an angle bar
• Run FEM to determine effect of different variables
• Deadlines
