In order to understand the damage effect of the ground-explosive bomb on the building, the factors affecting the power of the invading warhead are analyzed. The finite element model and the material model were constructed. The explicit dynamics software AUTODYN was used to calculate the damage effect of the projectile at different speeds, static explosion, and intrusion on concrete buildings. The difference between projectile intrusion and static explosion at different speeds was analyzed. The crack propagation contrast of the top of concrete building at different speeds, and the numerical simulation results are obtained. The calculation results show that the analysis can provide a reference for the design of the warhead and the design of the target protection.
