The goal of this study was to develop a motion-based injury criterion for brain injuries derived from the material response of the brain tissue, under the assumption that impact response of the brain tissue can be characterized by a standard linear solid. Focus was given to brain injuries that are deemed to correlate with the strain of the brain tissue, including subarachnoid hemorrhage, intrac...

In motor vehicle crashes, occupants who are elderly and obese are at increased risk of death and serious injury compared with young, non-obese adults. However, current procedures for evaluating vehicle safety designs are mainly conducted with crash test dummies and computational dummy/human models representing only a few sizes of young and non-obese occupants, namely large-male, mid-size male, ...

Presented paper discusses new approach to EES parameter determination in frontal car crash based on the tensor product of Legendre polynomials. In this Subcompact Car Class was analyzed using that method. Data used perform analyses introduced taken from National Highway Traffic Safety Administration (NHTSA) database. Such database consists considerate number test cases along with various inform...

Introduction: The surgical management of chronic frontal sinus disorders remains a challenge for rhinologists. The aim of this study was to evaluate the result of Draf III in a series of patients who underwent this procedure.   Materials and Methods: Twenty patients were included in this study. Demographic data, history of prior surgery, asthma,  aspirin sensitivity and Lund–Mackay score were r...

A finite element (FE) model based on a 2010 Toyota Yaris passenger sedan was developed through the process of reverse engineering at the National Crash Analysis Center (NCAC) of The George Washington University (GWU). This detailed FE model was constructed to include full functional capabilities of the suspension and steering subsystems. This model was validated by comparing the simulation of t...

THIS ihteresting case of injury to the visual pathway presented a difficult problem' in localisation and in pathology. I can find no case quite comparable to it in the literature, and it has the added advantage that ...

A number of staged impacts performed by our group with the aid of a test device representing a low-mass vehicle (LMV) indicates that a rigid-belt body (RBB) is a valid means for providing adequate occupant safety also for LMVs in the strict sense (curb mass less than 600 kg). The RBB concept raises the problem of compatibility, however. Ideally, the deformability of car front structures should ...

More than half of occupant lower extremity (LEX) injuries during automotive frontal crashes are in the knee-thigh-hip (KTH) complex. The objective of this study is to develop a better understanding of the KTH injury mechanisms and injury thresholds using a new finite element (FE) human model. A detailed biofidelic occupant LEX FE model is developed based on the component surfaces reconstructed ...
