A Nonlinear Viscoelastic Model for Silicon Rubber Foam Cushion Considering Time-Varying Evolution Characteristics
摘要
Abstract
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.关键词
