Abstract

The behavior of delaminations and fiber breakage resulting from three-point bending test is a major concern in the study of composites. This research focused on analyzing fiber breakage and delaminations in advanced placed ply composite laminates through a series of tests. In order to compare simulation results with the experimental data, the cohesive zone model was implemented for analyzing the damage in the model. The results of the simulation were validated using experimental results. The predicted damage initiation load exhibited an approximate 20% deviation from the actual test loads and the discrepancy stems are analyzed.
