The dynamic mechanical responses and damage development of cross-ply composite
laminates under repeated low-velocity impact are investigated through finite element …

Hat-stringer-stiffened composite panels have been widely used in aircrafts. Accurate failure
analysis of them is important for the safety and integrity of the fuselage. During the service …

Metal/composite hybrid square tubes that combine the advantages of low-density of
composite with low-cost of metal provide a potential energy absorption device for …

Low velocity impact events significantly reduce the mechanical performance of composite
structures even though the damage might be barely visible. Numerical simulations can be …

This work deals with the development of an improved numerical model, based on the explicit
finite element method, aimed at investigating the energy absorption capabilities of a full …

Simulating polymer-based composite structures under low-velocity impact and sequencing
compression after impact loading, is a complex problem that requires using well-suited …

Impact resistance and damage tolerance after impact are important performance reference
indices in the structural design of composite stiffened panels. The damage evolution and …

Impact locations play a critical role in determining the residual performance of the composite
stiffened panel, since the local damage behavior at different locations is not identical. The …

To improve the torsional buckling resistance and enhance the load-bearing capacity and
ductility of H-shaped steel beams with carbon reduction materials, the concept of combining …

Sandwich composites are prone to delamination and fracture during service when exposed
to external low-velocity impact. One hindrance to overcome before a broader deployment of …
