WebJul 2, 2024 · Blunt head trauma was estimated using backface deformation (BFD). The Wz.93 combat helmet was used for testing. Analytically, dependencies were derived to determine the scope of BFD. WebThe model was developed using the scanned geometry data from the experimental headform and includes the metal frame, Roma Plastilina clay and a full combat helmet with pads. Subsequently, ballistic impact simulations using the model were performed and the backface deformation signatures of the helmet are recorded in the clay.

WebMar 31, 2014 · The original Army protocols for backface deformation (BFD) were based on binary (0-1) data. The BFD measurement at each location was compared against its specified threshold, and the outcome was scored as a “1” (failure) if it exceeded its threshold. This original plan was based on 20 shots; if no BFD measurements exceeded … WebInRangeTV did a video a while back. They suffer from unacceptable backface deformation when compared to legit ballistic helmets like Ops-Core, among a few more minor issues like having a greater tendency for the shitty hardware to break easily. For the price, you're much better off buying a Galvion/Revision helmet or a Gentex TBH-IIIA. states that have scorpions

WebBallistic helmets that defeat the threat can still cause head injuries by striking the head with its backface deformation (BFD). In this study the relationship between kinetic energy … WebMeasuring Backface Deformation. Helmet BFD, defined as the maximum depth in clay as measured from the original clay surface at the intended impact location, is assessed … WebOps-Core is committed to designing advanced performance capabilities for the elite warrior.
