| description | 3D woven composites have been widely used in aerospace field. It is of great engineering value to study the damage mechanism of C/C woven composites with openings under tension and compression. A mosaic finite element model of C/C woven composite with opening-hole is established, and the progressive damage analysis under tensile and compressive loads is performed to study the mesoscopic damage model of opening plate. In the finite element modeling, a mesoscopic finite element model is established based on the mesostructure of the material in the perforated area of the open-hole plate, and the rest is equivalent to a uniform model. The failure criterion based on meso-mechanics is used to predict the ultimate load and strength of open-hole plates under tensile and compressive loads, and the damage process is studied. Based on the simulation, the damage initiation occurred in many areas of the warp yarn due to the stress concentration in the contact area between the binder and the warp yarn. And the damage area of the open-hole plate exhibited an ‘X’ shape expansion both under tensile and compressive loads. |
