The Composite Structure Compared To The Mechanical Analysis Of High-speed Impact

This paper firstly presents the impact basic theories and the applying method for the general engineering FEM software system-ANSYS, then the preliminary numerical simulation has been conducted in the mechanical process of the laminated composite plates subjecting to the impacting loads, the higher-velocity hit between the composite shells and the metal structures, the bird-impact radar cover experiment is also included. Changes of the mechanical values in subjecting to different impact loads are also analyzed. The result of numerical simulation offers a theoretical reference for the experiment of anti-bird radar cover.
