This contribution is a review of past and current research progress on dynamic response of composites sandwich structures subjected to low-velocity impact. To obtain a comprehensive overview of the current state-of-the-art published works, impact responses on sandwich structures are broadly classified into two main groups, high-velocity and low-velocity impacts, with the focus on low-velocity impact. A summary of some of the commonly used theoretical solutions for low-velocity impact is provided and described in some details. The response of low-velocity impact has been determined based on mass ratio, which is defined as the ratio of the impact mass to effective mass of the structural component. As a result, the response under low-velocity impact was further subdivided into three possible categories, namely, large, small, and medium mass impacts. For each category of impact, currently available suitable solutions are discussed in details. To classify the response of low-velocity impact and also to explore...

Metal fiber porous materials with intrinsic properties of metal and functional properties of porous materials have received a great deal of attention in the fundamental research and industry applications. With developments of the preparation technologies and industrial requirements, porous fiber metals with excellent properties are developed and applied in many industry areas, e.g., sound absorption, heat transfer, energy absorption and lightweight structures. The applied research progress of the metal fiber porous materials in such application areas based on the recent work in our group was reviewed in this paper.
