Tensile
and Buckling Analysis of Polymeric Composite Columns |
This
research studied the critical load of composite columns
theoretical and numerical by using ANSYS14 package depended on
experimental tensile properties of composite specimens. The
composite specimens were prepared by hand lay-up technique made
from unsaturated polyester reinforced with glass fibers with
different fiber volume fraction Vf, aspect ratio (L/T), and
angle of fibers for coarse and fine woven fibers.
The critical load that obtained by using program (ANSYS 14) have
also shown a good agreement with results that were obtained
theoretically and the maximum difference was (0.7%).
The results show that the maximum value of the critical load can
be observed at Vf =11%, L/T = (3.5) and θ = (0º/90º) for fine
woven fibers was (622.115N). Also its found the maximum critical
load for coarse woven fibers can be observed at Vf %=8%,
L/T=(3.5) and θ = (0º/90º) was (486.887N). Also the observed
values of tensile properties and predicated values are scattered
close to the (45˚) line. |
