Thickness-dependent energy dissipation characteristics of laminated composites subjected to low velocity impact

This study investigates the low velocity impact properties such as damage thresholds, critical energy thresholds and damage process of laminated composites. Damage thresholds of Hertzian failure and main failure corresponding to woven and unidirectional Glass Fiber Reinforced Polymer laminates in varying thicknesses from 2 mm to 8 mm are determined through impact tests with nominal impact energies of 4, 6, and 8 J/layer. Hertzian failure and...
