What happens when a bullet hits your helmet?

The findings indicate that when a bullet impacts on the bullet-proof helmet, it has a higher probability of causing brain displacement and intracranial high pressure. Intracranial pressure higher than 235 kPa could result in serious brain injury, and the tensile fracture stress for the skull is around 75 MPa [28].

Can someone survive blunt force trauma to the head?

A blunt force head trauma is a severe injury to the head. The main concern with this type of injury is that it could cause a traumatic brain injury (TBI). This is an extremely serious injury that can cause life-long health issues and even death. Head injuries require significant monitoring by medical professionals.

How much back face deformation is lethal?

If this “back face” deformation is beyond 44 mm, for example, it is generally deemed unsuitable for armor materials that are worn directly on the body. Such a large amount of deformation could cause serious injury or be lethal, even though the threat may not penetrate the skin [27].

What is the most common cause of blunt trauma to the head?

Motor vehicle accidents are the most common cause of blunt force head trauma. When vehicle accidents result in death, there is almost always evidence of blunt force trauma somewhere on the body. Other common causes of blunt force head trauma include sporting incidents, physical assaults, and falls.

How does blunt head trauma cause death?

Head trauma and severe loss of blood are the most common causes of death due to blunt traumatic injury. Severity of the injury depends on the mechanism and extent of injury. Typically, a large force applied to a sizable area over several minutes will result in vast tissue damage, which increases the chance of death.

How does blunt trauma affect the brain?

The long-term effects caused by traumatic brain injury may include speech and language problems, chronic headaches, changes or loss of vision, taste or smell and coma. The damage can be worsened by internal bleeding of the brain.

What is backface deformation?

In simple terms, backface deformation refers to the backside of the plate, where the bullet is caught and prevented from exiting and penetrating your body; it’s the indent caused. When you’re shot, the backface is deformed.

What is Backface signature?

Backface signature injuries are lacerations that occur due to blunt trauma. As a working real-life definition, backface signature injuries can be defined as open, penetrating wounds that occur even though the bullet did not penetrate the vest.

What is a bump helmet?

A bump helmet is used to prevent bumps on the head. But, selecting a good bump helmet is not as easy as knowing the general purpose of the gear. The best models around are those that will not only serve as a hardhat but will also stop piercing and be able to attach gear on.

What is behind helmet blunt trauma (bhbt)?

The mechanism of Behind Helmet Blunt Trauma (BHBT) caused by a high-speed bullet is difficult to understand. At present, there is still a lack of corresponding parameters and test methods to evaluate this damage effectively.

What is the best ballistic helmet to use?

The NeoSteel™ Helmet is the best ballistic helmet to use if you’re concerned about behind armor trauma. The NeoSteel™ Helmet is not capable of significant backface deformation, and its stiff shell spreads the kinetic energy load of a projectile impact across the entire padding system.

Does the Neosteel™ helmet have significant Backface deformation?

The NeoSteel™ Helmet is not capable of significant backface deformation, and its stiff shell spreads the kinetic energy load of a projectile impact across the entire padding system. In contrast, with a lightweight composite helmet, backface deformation is a real concern, and is associated with injuries up to and including skull fracture.

What are the risks of wearing a helmet?

In contrast, with a lightweight composite helmet, backface deformation is a real concern, and is associated with injuries up to and including skull fracture. In any case, with either helmet, neck injuries resulting from head acceleration are very unlikely.
