SHOCK WAVE PROPAGATION IN THE GAP BETWEEN THE COMBAT HELMET-HEAD ASSEMBLY

Military personnel frequently encounter blast in battlefields. In a far-field regime, shock waves alone can cause an invisible wound in the brain by causing hemorrhage or concussion, which is termed as blast-induced Traumatic Brain Injuries (bTBI). It is essential to identify the location of pressure peaking points due to shock reflections that are essential in designing better quality combat helmets to mitigate bTBI. So this study mainly focuses on understanding the pressure peaking due to shock waves in the gap between helmet and head for front and bottom blast loading directions.
