摘　　要：利用三维非线性动力有限元程序ANSYS/AUTODYN研究了剪切模量、雨贡钮弹性极限、拉伸强度、陶瓷碎块的抗压强度以及抗损伤能力等因素对Al2O3陶瓷抗杆式穿甲弹性能的影响。结果表明,Al2O3陶瓷抗穿甲质量防护系数对剪切模量最敏感。Influence of shear modulus,hugoniot elastic limit,hydrodynamic tensile limit,compressive strength of the fracturedceramic and anti-damage property on the ballistic-protection performance of Al2O3 ceramic was studied by the use of the ANSYS/AUTODYN-3D software. Results indicate that mass efficiency factor of Al2O3 ceramic is sensitive to the shear modulus.
