| 英文摘要 | The oxide/oxide ceramic-matrix composites exhibits superior mechanical properties and complex nonlinear behavior in a high-temperature environment. This paper developed a constitutive model utilising an elastoplastic modeling framework to represent the nonlinear mechanical response of the thermal shocked ox/ox-CMCs under off-axis tensile loading accurately. The model captures main features such as the effects of the thermal shock temperatures on material response. The main interest of the proposed model is the ability to predict the nonlinear mechanical response for thermal shocked ox/ox-CMCs, which is of importance for industrial applications. The validity of the constitutive model is verified by analysing the mechanical behavior of an open-hole specimen and comparing the simulation result with the experimental data. |
