KAYLA KRUPER 11/30/2015 FINITE ELEMENT STUDY TO COMPARE THE PERFORMANCE OF COMPOSITE AND STEEL 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

ANGLE BAR GEOMETRIES Thickness (t) is 0.25”

ANGLE BAR PROPERTIES Material Properties of Fiberglass Material E 1 (x 10 6 psi) E 2 (x 10 6 psi) v 12 G 12 (x 10 6 psi) G 13 (x 10 6 psi) G 23 (x 10 6 psi) Glass-reinforced plastic (fiberglass) Material Properties of Steel Material Young’s Modulus E (x 10 6 psi) Density (lb/in 3 )Poisson’s Ratio Steel

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
