CAREER: High Speed Grinding of Ceramics: Process Simulation and Damage Assessment

对结构陶瓷的高速磨削进行了数值模拟和实验研究，重点研究了相关的损伤机理。计算工作的主要目标是包含惯性和速率效应，并捕捉复杂的动态断裂过程。实验工作用于验证，并执行通常用于表征陶瓷材料可加工性的高应变划痕试验。整体的努力带来了高效的高速研磨过程，从而提高了生产率，并将亚表面损害降至最低。*

The numerical and experimental investigations of high-speed grinding of structural ceramics are performed with emphasis on the associated damage mechanisms. The primary goal of the computational effort is the inclusion of inertial and rate effects and the capture of complex dynamic fracture process. The experimental effort is used for validation and high strain version of the scratch test commonly used to characterize the machinability of ceramic materials is performed. The overall effort results in an efficient high speed grinding process which leads to enhanced productivity with minimal subsurface damage.***
