Simulation of concrete tensile failure under high

2016-10-1  For realistic simulation of concrete behavior under dynamic loading, it is essential that this rate dependency be considered. This paper proposes a three-dimensional lattice model—formed from rigid-body-spring elements—that incorporates the rate dependency of concrete strength, elastic modulus, and fracture energy.

Analysis of Concrete Tensile Failure using Dynamic ...

2021-4-1  In this study, the damage model and proportional damping algorithm are applied to the dynamic PDM to analyze concrete tensile failure under high strain rate loading. Accurate material modeling for these damage and damping behaviors is essential to simulate concrete dynamic fractures involving tensile failure.

This study presents the use of the dynamic particle difference method (PDM) to analyze tensile failure in concrete subjected to high loading rates. In general, strong form-based meshfree methods suffer from limitations pertaining to the material modeling of concrete because concrete exhibits both softening and damage behaviors that initiate crack growth under an impact load.

A Micromechanical Model for Simulation of Rock

2020-7-24  DIF values for high strength concrete under tensile and compressive loading were measured and are reported in Fig. 18 . From this figure, it appears that quasi-brittle materials such as concrete demonstrate different rate dependency behaviour under compression and tension; they are more sensitive to the applied strain rate in tension.

Effect of Loading Rate on Tensile and Failure Behavior

In order to investigate the effect of the loading rate on the tensile behavior of concrete, a series of three-point bending tests of concrete specimens under different loading velocities (0.1 mm/min, 90 mm/min, 120 mm/min and 150 mm/min) were conducted. The profile of the loading rate is detailed in Figure 6. All tests were divided into four groups, with three specimens for each group.
