抄録

The authors have proposed a visco-elasto-plastic suspension element method using a non-continuum model to simulate dynamically the fracture behavior of concrete. In this paper, in order to investigate the applicability of this analytical method to the analysis of the fracture behavior of concrete, the axial compressive test and the tensile splitting test under high-speed loading using 2-D and 3-D model specimens of concrete are carried out The experimental and analytical results are compared, and it is confirmed that the fracture phenomenon of concrete under high-speed loading can be expressed numerically by this analytical method.
