Abstract

A finite element model of the rat's head was developed to improve the knowledge on traumatic brain injuries. A parametric study was conducted on the mechanical characteristics of its anatomical components. A correlation was then established between observed injuries on one hand and intracranial stresses on the other. This result is mainly based on experimental well-defined impacts that generate high rotational accelerations of the head in the sagittal plane. This approach shows the power of numerical tools for better understanding of injury mechanisms and thus for design of protection devices against extreme mechanical loadings of the human body.
