High Speed Impact Analysis of Kevlar-Fabrics(2008)
Description: High speed impact analysis of multi-functional nano-Kevlar fabrics under ballistic impact loading to explore the impact energy absorption mechanism.
Bird Strike Analysis of Leading Edge of WIG craft (2008)
Description: Nonlinear bird strike analysis on the composite wing structures based on FAA requirement for commercial aircraft. ALE(arbitrary Lagrangian-Eulerian) method and SPH(Smooth Particle Hydrodynamics) method were employed to simulate large deformation post impact behavior of the bird and composite sturcutre.
