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.

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.

The dynamic tensile failure modes of a single-edge notched concrete specimen and the L specimen under different loading rates are numerically investigated. The simulation results indicate that dynamic failure pattern and the direction of crack propagation of concrete have pronounced loading rate sensitivity.

In the present paper, mesoscale model is adopted to analyze the dynamic tensile behaviour of concrete at high strain rates; especially, the effects of the ITZ on the failure properties are analyzed. In the mesoscale model, to simplify the problem, the shape of the coarse aggregate is assumed to be circular and the ITZ zone is modelled as a thin ...

Crack growth of concrete beam under dynamic tensile loading is a typical discontinuous problem. It is difficult to realize the process of crack propagation using the conventional finite element method, but the extended finite element method (XFEM) is an effective method to analyze the fracture developed in recent years. This paper introduces the basic principle of XFEM and the analysis method ...

2020-10-10  The tensile-failure problems of rock bolts are complicated. Furthermore, the theoretical analysis method is difficult to use in solving this issue, and the model test method cannot be widely used because of its high cost [22, 23].This requires new studies to properly consider the failure in tension of those rock bolts caused by excessive deformation (elongation).
