• The propagation of blasting wave driven by differently shaped explosives in concrete was simulated by LS-DYNA with Johnson-Holmquist-Cook constitute model (JHC). The propagation features of the stress wave and the distribution of damage in concrete were analysed based on the numerical results. They show that the difference in propagation of blast waves and damage distributions due to the shape of explosives is evident in close area of explosion but diminishes with the increase of the distance away from the explosion centre.
