“…Side impacts contributed to almost one-quarter of all severeto-fatal head injuries (Morris et al, 1995). In the cited study, head contact within the interior vehicle structures was identified as an impact source, paralleling current data.…”

“…The forehead impact site was chosen to simulate an unrestrained motor vehicle occupant in a frontal impact, a scenario prevalent during that period (Sances & Yoganandan, 1986). Reflecting the current vehicle environment, recent epidemiological studies, full-scale crash tests, and clinical reports indicate the occurrence of head injuries in lateral crashes (Gennarelli et al, 2002;Morris et al, 1993). Biomechanical and crashworthiness communities continue to use frontal HIC in side impacts due to the paucity of tolerance and injury criteria for the human head in lateral impact.…”

This study was conducted to provide force and acceleration corridors at different velocities describing the dynamic biomechanics of the lateral region of the human head. Temporo-parietal impact tests were conducted using specimens from ten unembalmed post-mortem human subjects. The specimens were isolated at the occipital condyle level, and pre-test x-ray and computed tomography images were obtained. They were prepared with multiple triaxial accelerometers and subjected to increasing velocities (up to 7.7 m/s) using free-fall techniques by impacting onto a force plate from which forces were recorded. A 40-durometer padding (50-mm thickness) material covering the force plate served as the impacting boundary condition. Computed tomography images obtained following the final impact test were used to identify pathology. Four specimens sustained skull fractures. Peak force, displacement, acceleration, energy, and head injury criterion variables were used to describe the dynamic biomechanics. Force and acceleration responses obtained from this experimental study along with other data will be of value in validating finite element models. The study underscored the need to enhance the sample size to derive probability-based human tolerance to side impacts.

“…Their conclusions on the significance of head contact were supported by real-world epidemiological studies of Morris et al [30]. Backaitis, from an analysis of 755 cases of AIS 3+ injuries in motor vehicle crashes, reported only one injury was associated with no contact [15].…”

Abstract.The objective of this presentation is to discuss certain biomechanical aspects of head injuries due to blunt and penetrating impacts. Emphasis is given to fundamental data leading to injury criteria used in the United States (US) regulations for motor vehicle safety. Full-scale and component tests done under US Federal Motor Vehicle Safety Standards (FMVSS) are described. In addition, results providing occupant safety and vehicle crashworthiness information to the consumer from frontal and lateral impact crash tests are discussed with an emphasis on head injury assessment and mitigation. Recent advancements are presented in angular acceleration thresholds for quantifying brain trauma. In the area of penetrating impact, newer experimental techniques are described for a better understanding of head injury secondary to penetrating impacts, with specific reference to the civilian population.
