Postbuckling Behavior of Graphite/Epoxy Cloth Shear Panels with 45 deg-Flanged Lightening Holes.

Abstract

An experimental and finite-element analysis was performed on graphite/epoxy cloth plates subjected to static shear loading. Two specimens were tested to failure for each of three configurations: a solid panel, a panel with an unreinforced hole and a panel with a 45 deg-flanged hole. Both a static nonlinear analysis and a bifurcation-buckling analysis were performed for each of the panel configurations.
