A Study on the Interaction of Brain Impact With the Grounds of Different Material Types Available to Purchase

This paper proposes a parametric study of the response of brain, to human head impact with varied velocities as well as with the grounds of different material properties. The human head and its constituents are modeled using three-dimensional finite elements. The brain is made up of various elements that are modeled with a viscoelastic behavior. The ground is also assembled by finite elements. Five different velocities of impacts are considered based on realistic scenarios of human body falling due to gravity from five different heights. Three different materials for ground including wood, soil and rubber are considered. The simulation is run for a time history of 10ms after the incident. The intracranial coup pressure and shear stresses in the brain and various parts of the head are recorded. At the time of impact the peaks of the coup pressure and shear stress are observed to be proportional to the velocity of head and stiffness of the ground. Studies are conducted on the influence of the material of the impacting ground.
