The Influence of the Inclusion on the Fatigue Strength of Ceramic Bush

扫码查看
The Ceramic bush under the friction is analyzed with the finite element method, and a conclusion isdrawn that the area around the inclusion is the chief stress area in the matrix of the bush。As the external load increases ,the alternating stress around the area of the inclusion gradually becomes stronger andit leads to the reduction of the fatigue wear strength of the bush。
