Abstract To evaluate the explosion safety of intense light stun grenades, an explosion simulation model was established for their explosion bodies based on a LS-DYNA simulation platform. In this way, both the distribution rules and velocity variations of fragments can be analyzed. As indicated by the simulation results, their fragments are proven to be non-uniformly distributed as far as their sizes are concerned; and, low-velocity fragments with a large mass produced in the middle of the explosion body are the major sources of damage. Moreover, the corresponding radius of safety turns out to be 2.33m approximately. In a word, such an investigation provides a scientific basis for the R&D and applications of intense light stun grenades.
