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

对结构陶瓷的高速磨削损伤机理进行了数值和实验研究。计算工作的主要目标是包含惯性和速率效应，并捕获复杂的动态断裂过程。实验成果用于验证和高应变版本的划痕测试，通常用于表征陶瓷材料的可加工性。整体努力的结果是一个高效的高速磨削过程，以最小的次表面损伤提高生产率

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.***
