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

Abstract

The most practical composite building incorporates holes into its fundamental structure, which cause significant stress gradients. It is critical to understand how the cutout impacts the failure criteria of these composite plates while designing structures. Several factors, such as the percentage of fibre volume, loading angle, aspect ratio, and fibre orientation, are examined in this research to determine the failure loads around a hole in an E-glass/Epoxy composite plate. To achieve the objective, two approaches are used. I-Analytical, MATLAB version 17 was used to implement Lekhnitskii's solution, and the resulting generalised formulation is programmed to provide analytical findings. The II-Numerical team used the ANSYS 17.2 finite element tool to build the simulation model.
