大尺寸SHPB试验C30混凝土试件合理长径比研究
Study on the Reasonable Ratio of Length to Diameter of C30 Concrete Sample of Large Diameter SHPB Experiment
本文针对大尺寸SHPB试验系统对混凝土准脆性材料进行试验研究中如何确定试件的长径比进行了研究。通过试件SHPB冲击试验对C30混凝土不同长径比情况下的试验数据进行了分析，在此基础上对照数值模拟分析结果，确定了准脆性材料C30混凝土在大尺寸SHPB试验系统中的合理长径比范围，分析结果对相关情况下试验研究有参考价值。
his paper makes a study on how to confirm the ratio of length to diameter during the process of the experimental study on the quasi-brittle material, concrete, by means of large diameter SHPB experimental system. Through the SHPB impact experiment, the data with different ratios of length to diameter of C30 concrete is analyzed, and on this foundation, contrast to numerical simulation analysis results, the reasonable range of the ratio of length to diameter of C30 concrete is confirmed, the analysis result is of reference value to correlative experimental studies.
