Stress concentration in composites laminates
A numerical stress analysis using Boundary Element Method (BEM) was carried out on unidirectional orthotropic composite laminates. The study was to analyse the location and magnitude of stress concentration around the central hole of the laminate. The materials studied in this numerical simulation a...
