Ballistic impact on composite panels is studied in this work both experimentally and computationally. The purpose was to develop computational methods to analyze a high speed jet engine fragment impacting on composite targets. 12 inch by 12 inch laminated panels with 8, 16, and 32 plies and the standard +-45, 0 /90 degree stacking sequences were considered. With the nominal ply thickness of 0.0...

24 Reinforcement of fibrous composites by stiff particles embedded in the matrix offers the 25 potential for simple, economical functional grading, enhanced response to mechanical 26 loads, and improved functioning at high temperatures. Here, we consider laminated plates 27 made of such a material, with spherical reinforcement tailored by layer. The moduli for this 28 material lie within relati...
