Analysis of Composite Plate Failure Under Arbitrary Tension Load with Central Opening Hole

Abstract

The most feasible composite construction has holes built into its basic structure; these holes result
in strong stress gradients. In the construction of buildings, it is crucial to comprehend how the
cutout affects the failure criterion of such composite plates. The failure loads surrounding a hole
in an E-glass/Epoxy composite plate are investigated in this study under the influence of numerous
variables, including fiber volume percentage, loading angle, aspect ratio, and fiber orientation.
Two methods are employed to accomplish the goal. I- Analytical, Lekhnitskii's solution was
implemented using MATLAB version 17, and the generalized formulation that was thus obtained
is coded to produce analytical results. The simulation model was created by II-Numerical using
the finite element program ANSYS 17.2.
