NUMERICAL MODELLING OF IMPACT ON 3D COMPOSITE STRUCTURES (original) (raw)

This paper explores the numerical modeling of impacts on 3D composite structures, particularly focusing on the effects of low-velocity bird and hailstone impacts typical in aerospace applications. The research highlights the significant advantages of composite materials, such as weight reduction leading to fuel savings in commercial aviation. It investigates the mechanical properties of these materials under simulated impact scenarios, detailing methodologies for assessing damage and stress responses through numerical simulations and experimental observations. Findings indicate that while composites offer structural integrity benefits, their performance can be significantly influenced by environmental conditions and impact characteristics.
