Stress analysis in composite laminates
A numerical stress analysis using the Boundary Element Method (BEM) was used to analyze the stress intensity factor of the orthotropic unidirectional lamina with a center circular hole under steady tensile loading. AS4/3502 Graphite-Epoxy was used in this experiment. Results of the location, magnit...
