摘要
The stress intensity factors and stress conditions of machining cracks are analyzed by fracture mechanics on the basis of honing characteristics and of brittle ceramic mechanical behavior.Because the honing incidental tensile stresses effectively decrease the critical grinding stresses and increase the stress intensity factors of machining cracks,the honing process can be carried out easily.The results show that honing can be an efficient machining method for brittle materials.
根据珩磨加工特性和脆性陶瓷材料力学性能，应用断裂力学理论，分析加工表面裂纹尖端的应力强度因子及应力状态．珩磨附加拉应力增大陶瓷材料加工表面裂纹尖端的应力强度因子，降低陶瓷材料的临界磨削力，使陶瓷材料的去除容易进行．研究表明，珩磨可作为脆性陶瓷材料的一种高效加工方式．
