The rear face is deflected and then goes into tension. In the case of strong fibers, it is also important to address their strain to fracture since the product of strength and strain to failure is proportional to the energy absorbed. Frontiers in Head and Neck Trauma: Int J Impact Eng 15 4: The WSTC predicts injury as a function of the average acceleration and the duration of the acceleration. This penetration provides a way around this obstacle. To fully understand the mechanisms by which TBI occurs, it is critically important to understand the effects of the loading environments created by these threats.
In support of this theory, research has shown that diffuse injuries caused by rotation are greatest near the surface of the brain, where the rotational motion is the greatest; they are reduced near the center of mass, where the rotational motion is the least 28 , A number of studies have used both testing and simulation to assess the effects of protective equipment, primarily helmets and face shields in preventing blast-induced neurotrauma. This paper reviews the elements of physics of the different types of TBI. Conflict of Interest Statement The opinions belonging to and expressed by Geoffrey Ling herein belong solely to him.
