概要
- 論文の詳細を見る
In order to examine mode-I & II type fracture behavior of ceramic joints, the interface element was proposed as a simple model which represents the mechanism of failure in an explicit manner. It was applied to the analyses of four point bending tests and asymmetrical four point bending tests for SiC/SiC composite specimens joined by ARCJoinT^<TM>. By using a combined interface potential, which is a coupled function of opening and shear deformations, both the bending and asymmetrical bending tests were simulated. From comparison with experiments, surface energy at the interface between the joint and composite was estimated to be about 30N/m regardless of the fracture mode.
