Experimental and Finite Element Modeling of Penetrating Traumatic Brain Injury
To study penetrating traumatic brain injury biomechanics, a full metal jacket 9-mm handgun projectile was discharged into a transparent brain simulant (Sylgard gel). Five pressure transducers were placed at the entry (two), exit (two), and center (one) of the simulant. High-speed digital video photography at 20,000 frames per second (fps) was used to capture the temporal cavity pulsation. Press...
متن کاملA QCT-Based Nonsegmentation Finite Element Head Model for Studying Traumatic Brain Injury
In the existing finite element head models (FEHMs) that are constructed from medical images, head tissues are usually segmented into a number of components according to the interior anatomical structure of the head. Each component is represented by a homogenous material model. There are a number of disadvantages in the segmentation-based finite element head models. Therefore, we developed a non...
متن کاملFinite Element Modelling of Impact-induced Axonal Injury in Sheep
This paper describes a numerical study of axonal injury caused by an impact to the head of the anaesthetised sheep. In the model, described in Anderson et al. (2003), injury is closely related to the peak impact force and to kinematic measurements, particularly the peak change in linear and angular velocity. A three-dimensional finite element model of the sheep skull and brain was constructed t...
