A review is presented of the existing finite-element (FE) models for the biomechanics of human head injury. Finite element analysis can be an important tool in describing the injury biomechanics of the human head. Complex geometric and material properties pose challenges to FE modelling. Various assumptions and simplifications are made in model development that require experimental validation. More recent models incorporate anatomic details with higher precision.

The proposed modeling approach would provide a tool to improve the helmet design on a biomechanical basis and calculate the responses of the head–brain during a top impact when wearing a construction helmet.

Finite element analysis of brain contusion: An indirect impact study

Shear strain theory appears to better account for the clinical findings in head injury when the head is subjected to an indirect impact, and predictions of cavitation theory that a pressure gradient develops in the brain during indirect impact are supported.

Biomechanics of temporo-parietal skull fracture.

Modified Bilston nonlinear viscoelastic model for finite element head injury studies.

The proposed model will be especially useful for application to FE analysis of the head under impact loads, and incorporating the nonlinear viscoelastic constitutive law for brain tissue into a commercial FE code.

Understanding how a sport-helmet protects the head from closed injury by virtual impact tests.

The obtained results suggested that, if the helmet shell already has adequate strength to resist excessive deformation and fracture, further increasing shell stiffness and strength would not considerably reduce intracranial pressure and brain strains; to reach the maximum protection with the available materials, the key is to effectively use the second stage in the stress-strain history of the liner foam material.

In vivo tissue-level thresholds for spinal cord injury

Despite the prevalence of small animal models in the neuroscience community used to study SCI, there have been no published analyses of in vivo models of SCI and Finite element analysis has become an important and cost effective tool to investigate the biomechanics of trauma.

An ellipsoidal model for studying response of head impacts.

In this model, the effect of Hertzian contact stiffness and local shell stiffness are combined to derive explicit equations for impact duration, the peak force transmitted to head, and the head injury criterion.

Biomechanical modeling and computer simulation of the brain during neurosurgery

A physics‐based modeling approach is adopted and the brain deformation in mechanical terms is described, which can be computed using a biomechanical model, by solving a continuum mechanics problem.

Influence of FE model variability in predicting brain motion and intracranial pressure changes in head impact simulations

The results indicate that, despite the fundamental differences between these six model formulations, the comparisons with the experimentally measured pressures and relative displacements were largely consistent and in good agreement and may prove useful for those attempting to model real life accident scenarios.

Dynamic response of the human head to impact by three-dimensional finite element analysis.

Interestingly, the model predicted higher contre-coup pressure in the frontal lobe (from occipital impact) than that predicted in the occipitals region from frontal impact, which supports clinical findings of contre -coup injury being more likely to result from occipITAL impact than from frontalimpact.
