摘要
以断裂力学为基础,采用分子论观点描述了天然橡胶/丁苯橡胶的动态疲劳过程。结合断裂力学的参数β和C0,对S~N曲线特征和断口形貌进行分析和比较。
Based on fracture mechanics, the dynamic fatigue mechanism of NR/SBR blends was studied. The mechanism was described with the standpoint of molecular theory. Analysis and comparision are made on S~N curves to characteristic the fatigue failure with parameters of fracture mechanics β and C 0. It provides the theorytical basis for the selection of optimum blend ratio.
