| Abstract: | The experimental method on the dynamic splitting tensile test of concrete is introduced in the present paper. By using the FEM code LS-DYNA, the numerical simulation on the dynamic splitting tensile test of concrete is carried out. The numerical simulation gives the differences between the stress distributions in the concrete specimen under different kinds of loading case. The validity of dynamic splitting tensile test is verified. Some conclusions on improving test method are given. |
