Abstract Dynamic simulation and design of complex composite structures with energy-absorbing lattice are critically
important for aircraft applications. In this study, high-velocity impact behaviors (deformation and damage
modes) of sandwich composite structures with multilayer lattice are numerically studied by using explicit
dynamics computation. First, the modeling strategy for sandwich composite panels with the multilayer
lattice and foam core is developed by using Finite Element Method (FEM). In FEM model, the beam, shell,
and solid elements are applied together for both the computational accuracy and efficiency. The unit cell
model of the lattice is used considering the More >
