【摘要】 利用有限元数值分析法对混凝土一维拉伸层裂实验进行了探讨,并采用Holmquist-Johnson-Cook混凝土本构模型进行计算.结果显示试件截面应力分布均匀,满足一维拉伸层裂实验中的截面应力均匀的假设;在对比实验和数值模拟结果的情况下,模拟结果也验证了实验的可行性.更多还原

【Abstract】 In this paper,the numerical analyses on large concrete under dynamic tensile stress are investigated.A computational constitutive model for concrete Holmquist-Johnson-Cook is used in this study;the results provide the stress on the specimen section is uniformity;and compared the results of the experiments and the numerical simulation,demonstrate the feasibility of the experiment.更多还原
