To manufacture some components bonding techniques could be used. In order to understand the possible damage mechanisms of adhesive joint with CMC materials, experimental and numerical analysis using a four-point bending test is presented here. The numerical studies are performed using a continuum damage model for the behavior of the substrate and a cohesive zone model for the behavior of the interface between the composite and the bond. The results of the simulations are presented and discussed. © 2020 The Authors. Published by Elsevier B.V.

Main text Due to their excellent mechanical properties at high temperatures, ceramic matrix composite (CMC) materials are often selected for applications in hot part of engines. Particularly, for some engine components subjected to moderate thermo-mechanical loadings (between 600°C and 800°C), oxide/oxide CMCs are a good alternative to metallic materials in regard to their interesting mechanical properties, thermal stability and cost. Exhausts are one example of possible structures with oxide/oxide CMC materials. In this kind of structure, several parts could be manufactured using bonding techniques. Hence, in the context of certification of CMC exhaust structures, it is necessary to characterize the behavior and to justify the good strength of bonded joint between two CMC plates. en access article under the CC BY-NC-ND license (http://creativecomm 23 European Conference on Fracture - ECF23 Experimental and numerical study of a woven oxide/oxide ceramic matrix composite adhesive joint using four-point bending test T.
