摘要：
The evolution of crack models based on fracture mechanics is reviewed. The brittle cracking model in Abaqucs is used to simulate the machining process of Al2O3. The result shows that it's appropriate to simulate the machining process of ceramics with fracture energy cracking criterion and post-failure constitutive relation in a smeared cracking representation. Although more works are needed in the future to resolve the mesh sensitivity. The material removal mechanism of ceramics is confirmed to be the brittle fracture regime. © 2016 Trans Tech Publications, Switzerland.
