Room: ES354
Abstract:
Dr. Aman Garg’s research on bird-strike-induced damage in bio-inspired laminates helps in understanding the damage mechanism in helicoidal composites and their superior impact-resistance properties compared to conventional laminates. His studies focus on using the concepts of finite element and smoothed particle hydrodynamics for modeling the bird-impact problems. Helicoidal laminates demonstrate superior energy dissipation through mechanisms such as crack twisting, delayed delamination, and progressive failure. These mechanisms promote damage delocalization, increase fracture energy, and suppress catastrophic failure. The study highlights how stress-wave redirection and enhanced shear deformation improve impact tolerance. Comparative analysis reveals that helicoidal laminates achieve significantly higher energy absorption and reduced damage concentration compared to conventional laminates. The findings provide critical insights into the design of next-generation impact-resistant structures for aerospace and protective applications.
