Cpg helmet backface deformation issue

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.
