计及时变演化特征的硅泡沫垫层 非线性黏弹性模型研究.

Based on the common theory of viscoelasticity, the mechanical model for aging silicon rubber foam cushion and the continuous loading prediction model for long-term stress relaxation silicon foam cushion, were obtained, in view of the 2 aging mechanisms, the nonlinear material characteristics, the loading process, the stress relaxation history, the aging effect and the degradation difference of each motion element of viscoelastic model. The mechanism of the model is clear, and it can reflect the information of the material service history and the corresponding effects on mechanics of the silicon rubber foam cushion.
