中文摘要：
针对真空橡胶的特性展开了MTS实验和SHPB实验,通过实验获得了材料的基本力学参数和应力-应变曲线,并对材料的变形行为、应变率相关效应和破坏特性作了必要的分析,在此基础上给出了材料的本构关系。结果表明,真空橡胶材料在准静态加载下,应力〈3MPa时,应变率效应不明显;在冲击载荷作用下,随着加载应变率的提高,应变率效应比较明显。
英文摘要：
Tests via MTS and SHPB on the properties of vacuum rubber were carried out.Basic mechanical parameters and stress-strain curve of them were obtained.The constitutive model was presented based on necessary analysis of deformation behavior of materials,strain-rate-related effects and destruction properties.It provides bases for engineering applications of these materials and further improvement.Results show： strain rate effect of vacuum rubber material is not obvious under quasi-static loading with stress less than 3MPa,which is more obvious under shock loading with increasing strain rate.
