Strength Analyses of Interference Fit between Ceramic Column and Metal Sleeve

Ceramic column and metal sleeve are often used together by interference fit. The stress distribution in brittle ceramics is different from that in metal. Two important factors for their connection strength such as interference value and the length of envelope surface are discussed in this paper. The results showed that interference value is the decisional factor for the strength of interference fit between ceramic column and metal sleeve, while the length of envelope surface impacts it slightly.
