Blast injuries are characterized by anatomical and physiological changes from the direct or reflective over-pressurization force impacting the body’s surface. The HE “blast wave” (over-pressure component) should be distinguished

WebREFLECTION OF BLAST WAVE AT A SURFACE INCIDENT AND REFLECTED WAVES. 3.21 When the incident blast wave from an explosion in air strikes a more dense medium such as the earth’s surface, e.g., either land or water, it is reflected. The formation of the reflected wave in these circumstances is represented in Fig. 3.21. This figure shows four ... Web13.1.7.2 HEIGHT-OF-BURST CURVES.
