Abstract

Abstract: The different understanding on the influential degree of the inertial effect does exist among researchers, and it has not been uniformly defined in dynamic tensile tests. The finite element numerical simulation method was employed to analyze the three typical dynamic tensile tests, without considering the real strain-rate effect in these models, where a constitutive model only considered the influence of hydrostatic pressure was used for modeling the specimen in these models. It is found that the dynamic tensile strength of concrete specimens in the three models mentioned is strengthened with the increase of loading strain-rate, owing to the inertial effect, while the increments of dynamic tensile strength obtained from these numerical tests are relatively small, compared with the corresponding experimental data. It means that the real strain-rate effect rather than the inertial effect is the main factor leading to the dynamic tensile strength enhancement of concrete-like materials.
