摘要 | The oxide/oxide ceramic matrix composite exhibits superior mechanical properties in high temperature environment. However, complex nonlinear behavior is not clarified for high performance applications. The present work developed an elastoplastic constitutive model considering variations of hardening behavior over the stress states by introducing a novel loading function. The model can account for heterogeneous initial yield and complex hardening behavior accurately and was verified from experiments under tension and compression conditions with various off-axis angles. The computational results agree with stress-strain responses containing softening up to failure under arbitrary in-plane loading conditions. |
