Description
Beams made of composite strengthened with graphene flakes are candidates for structures that face heat and sudden knocks. Tao Zhang and co-authors model how such a beam, built with slight geometric flaws, behaves under a low-speed impact when hot. The flakes are spread through the beam's thickness in a graded pattern, and material properties are estimated with standard mixing rules.
The team splits the impact into two stages, works out the contact force with a nonlinear law, and solves the beam's bending equations numerically step by step. They then vary the flaw shapes, the flake share, and the impact speed to see how each changes the beam's response, giving designers a map of which imperfections matter most.
