Abstract

A three-dimensional irregular lattice model was proposed and validated for concrete failure simulations under high loading rates. The validity of the fracture criterion and time integration method of the model was established. Subsequently the change in failure mode with different loading rates was examined via simulations of a modified-split Hopkinson pressure bar. In this paper, the model is validated, focusing on the rate-dependent response of the rheological unit and the failure mode change in concrete under impact loads. The results prove the capability of the model for simulating impact behavior of concrete in terms of the stress-strain relation with different loading rates, failure mode, and load-deflection curve.
