| Abstract: | This paper focuses on a simple numerical code to investigate the wave propagation and damage effect in a concrete slab. First, the derivations of governing equations and a cross-format central finite difference algorithm are presented. A self-written FORTRAN code is thus developed. Then, the Johnson–Holmquist-Concrete constitutive model is introduced and implemented into this code. Finally, after the code is verified against LS-DYNA, the mutual coupling of combined wave loadings and the induced compression damage in the concrete slab is explored in details. Numerical results show that this code is effective and can conveniently simulate the responses of concrete slab under different combinations of boundary loadings. |
