Simulation of SHPB Test on Concrete and Uniformity of Stresses

  • Split Hopkinson pressure bar(SHPB) tests on C100 and C80 concrete specimens were simulated with explicit dynamic finite element software LS-DYNA.The concrete specimens were simulated with the Johnson-Holmquist-concrete constitutive model.The stress-strain curves obtained by simulation are in good agreement with the experimental results reported in literature.Stress uniformity in the C100 specimen was analyzed.Result shows that the stresses in the specimen are not uniform in a short period before failure,which brings error to test result.
