Abstract
Due to their excellent properties, including low weight, high stiffness and strength and heat insulation, cellular materials are widely used in engineering applications, especially in the aerospace and defense industries, as energy absorption devices. To improve the performance of the cellular material, optimization of the material property has been attracted considerable research interest. Introducing a gradient in material parameters into the cellular material will significantly influence the behavior of the cellular material under impact loadings. Current paper summarizes our research progress on the investigation of the influence of the gradient on the behavior of the graded cellular material under impact conditions, including the deformation mode, underlying mechanism, energy absorption capacity and the transmitted force on the protected structure. Finite element simulation, analytical study and experimental investigation are involved in this research.
