In VBIED explosions, which parts cause the majority of fragmentation dispersal?

In VBIED blasts, the vehicle’s metal enclosure acts as a confined space that drives most fragmentation along the longitudinal axis. When the charge detonates inside the vehicle, the front end (engine bay, bumper area) and the rear end (trunk, rear structure) contain large, rigid components that shatter into high-velocity fragments. The energy is reflected and released outward from these ends, so the majority of shrapnel is projected forward and backward. The sides are often more shielded or less energetic in typical configurations, so they contribute fewer high-speed fragments. In short, the confinement and heavy components at the front and rear concentrate fragmentation dispersal in those directions.
