Split Hopkinson pressure bar(SHPB) tests are widely used for testing material mechanism behavior under high strain rates,A series of SHPB numerical tests were done based on K&C local concrete damage model,The stress-strain curves of the concrete specimens were reconstructed with the two-wave theory,and the damage of the concrete was analyzed.According to the comparison between the numerical and the test results,Proving K&C model can simulate concrete in concrete under high strain rate compressive mechanical behavior.Proving the increase of dynamic strength of concrete under the influence of structural effects.
