“…The parameters r 0 and 2γ were varied from 0.1 nm to 100 µm and from 3.0 x 10 -5 to 300 N/m, respectively. The shape parameter N was assumed to be 4 according to our previous researches [7,8].…”

“…The method treats the fracture phenomena as the formation of new surface during crack opening and propagation. Based on the fact that surface energy must be supplied for the formation of new surface, a potential function representing the density of surface energy is introduced to the finite element method (FEM) using cohesive elements [4] or interface elements [5][6][7][8][9]. So, in this research, to examine mode-I & II types of fracture behavior in SiC/SiC composite joint, the four point bending test and the asymmetrical four point bending test [10][11][12] were analyzed by using the interface element.…”

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 test and asymmetrical four point bending test for SiC/SiC composite specimen joined by ARCJoinTTM. By using a new type 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 30 N/m regardless of the fracture mode. Also, from the comparison between the predicted strength and the experiments for the tensile test of lap joint of SiC/SiC composites, it was found that the proposed method was considered to have a great potential as a tool to study the failure problems whose fracture type was a mixture of mode-I & II.
