Ballistic helmets design

The modem designs of ballistic helmets typically used by the American forces (and some adopted by other military forces) can be categorized into several helmet classes as follows ... 

The main characteristics of the materials, design and production of the combat helmet have been explored in detail. Finite element analysis and simulation tools have been revealed to be very useftil in ballistic-related research, as long as the researcher understands the complexity of the material model and high-velocity impact penetrators, and computational model experiments have been shown to be...

A helmet is a device used to protect our head from injury. There are many different types of helmets to be worn by bicyclists, race car drivers, police and military personnel. Helmets for military personnel and for police are made differently. Military helmets are designed for ballistic protections, whereas helmets for the police mainly provide protection against low-velocity trauma impact. There have many versions of helmets for both soldiers and police officers, and the latest are made from textile-reinforced composites (Roedel and Chen, 2007).
