Biomechanical Modeling of Traumatic Brain Injury
traumatic brain injury
Biomechanical modeling of traumatic brain injury (TBI) refers to the use of a computer model of the human head to simulate brain mechanical responses when the head is subjected to external blunt impact or blast exposure. The resulting tissue responses such as strain, strain rate, and pressure in specific regions of the brain can then be used to predict the occurrence of TBI.
A computational head injury model is composed of three basic constituents: model geometry, boundary conditions, and tissue material properties. With properly measured impact loading conditions as input for simulation, whole-brain biomechanical responses can then be estimated.
