Numerical Simulation on the Dynamic Splitting Tensile Test of reinforced concrete
The research for crack resistance was of RC was based on the split Hopkinson bar and numerical simulate software LS-DYNA3D.In the research,the difference of dynamic splitting failure modes between plane concrete and reinforced concrete were completed,and the change rule of tensile stress distribution with reinforcement ratio was studied; also the effect rule with the strain rate and the crack resistance was also discussed by the radial tensile stress time history curve of RC specimen under different loading speeds.The results shows that the reinforcement in the concrete can impede the crack extension,defer the failure time of concrete,increase the tension intensity of concrete; with strain rate of concrete increased,the crack resistance of RC increased.
