Anti-bullet Property of Encapsulated AD95 Al2O3 Ceramic Jubin Gao1,2,a, Yangwei Wang1,2,b and Fuchi Wang1,2,c 1School of Materials Science and Engineering, Beijing Institute of Technology, Beijing 100081, China 2 National Key Laboratory of Science and Technology on Materials under Shock and Impact, Beijing, 100081, China abitbinfly@163.com, bwangyangwei@bit.edu.cn, cwywbit@126.com Keywords: Encapsulation, Anti-bullet Property, Contact Pressure, Energy Dissipation.
In order to research the the effect of encapsulating materials on anti-bullet property and the difference of the property among the plates encapsulated by various materials, I fabricated some types of encapsulation armor plates with different encapsulated materials, such as 2024Al, SiCp/2024Al.
The encapsulated materials were 2024Al and SiCp/2024Al separately.
The encapsulating materials just played the role of reducing the damage area.
Encapsulating materials especially the cover materials in front of ceramic affected ballistic performance remarkably due to the strength and hardness of cover plates.

Introduction Despite having high tensile strength, most fiber-reinforced polymer (FRP) materials suffer from relatively low modulus of elasticity compared with steel.
Finite element model The type of unit Concrete unit The Solid65 unit in ANSYS is a three-dimensional solid element, specially developed as concrete, rock, and other materials’ simulation.
It can simulate the concrete materials specific to cracking, crushing and other mechanical phenomena, has a good pre-defined criteria for the destruction of concrete.
Constitutive materials and related parameters The steel rebar constitutive Bilinear Kinematic Hardening Plasticity model was adopted in Steel yield criterion.
