Damage Mechanism of Internal Defects in Ceramic Bearings Based on Discrete Element Method
This paper studies the damage form of the silicon oxide ceramic bearings with prefabrication defects by discrete element method,analyzes the influence of different inclination angles on crack development,explores the development characteristics of internal cracks and compressive strength of micro-defect ceramic bearings on the basis of the stress field and displacement field around the cracks to obtain the critical safety value,so as to provide guidance for the study of the mechanical properties and service lives of ceramic bearings.
