氧化铝材料的晶粒尺寸和纯度的范围内进行了小规模的动态冲击由尖锐的碳化钨弹丸在亚弹道速度。通过目视检查受冲击表面上的裂纹和次表面区域中的损坏来记录材料的抗断裂性。使用Cr3+荧光图谱检查每种材料中引起的残余应力和塑性变形。一个修改后的赫兹压痕模型的应力状态的材料中添加一个水泡场表示的应力引起的存在下的塑性区被发现准确地描述所观察到的裂纹下的材料的表面,以及表面上的径向裂纹。
Alumina materials with a range of grain sizes and purities were subjected to small-scale dynamic impact by sharpened tungsten carbide projectiles at sub-ballistic velocities. The resistance of the materials to fracture was recorded by visual examination of the cracking on the impacted surface and the damage in the subsurface region. The residual stress and plastic deformation induced in each material were examined using Cr3+fluorescence mapping. A modified Hertzian indentation model of the stress state in the material with the addition of a blister field representing the stress induced by the presence of the subsurface plastic zone was found accurately describe the observed cracks beneath the surface of the material, as well as the radial cracks on the surface.
