Abstract
The Advanced Combat Helmet (ACH) currently in use is designed for maximum protection against ballistic impacts and hard-surface collisions. It has been well-established now that the ACH provides relatively little protection against blast, and that a significant fraction of the soldiers returning from the recent conflicts suffer from traumatic brain injury (TBI). In the present work, an augmentation of the ACH, which involves the use of a polyurea (a nano-segregated elastomeric copolymer)-based external coating for improved blast protection is considered. To test the utility of this approach, blast experiments are carried out on instrumented head-mannequins. Three configurations of the head-mannequins are investigated: (i) unprotected; (ii) protected using a standard ACH; and (iii) protected using an augmented ACH. To provide additional insight into the problem of blast-wave interaction with a head-mannequin, a series of complementary combined Eulerian/Lagrangian transient non-linear dynamics computational...
