a spinal cord injury (sci) refers to any injury to the spinal cord or nerves at the end of the spinal canal that is caused by trauma instead of disease often causes permanent changes in strength, sensation and other body functions below the site of the injury. road traffic collision (rtc) or car crash occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other...

Car body deformation modeling plays a very important role in crash accident analyses, as well as in safe car body design. The determination of the energy absorbed by the deformation and the corresponding Energy Equivalent Speed can be of key importance, however their precise determination is a very difficult task. Although, using the results of crash tests, intelligent and soft methods offer an...

This work was performed to determine relations between car mass and driver injuries (serious or fatal) when cars of similar mass crash into each other head-on. This type of crash is examined because it is considered similar in some respects to a barrier crash. Data from the United States Fatal Accident Reporting System (FARS) are used to examine driver fatality likelihood as a function of car m...

Due to the extensive use of cars and progresses in the vehicular industries, it has become necessary to design vehicles with higher levels of safety standards. Development of the computer aided design and analysis techniques has enabled employing well-developed commercial finite-element-based crash simulation computer codes, in recent years. The present study is an attempt to optimize behavi...

In the present paper, employing a complete model of a passenger car, contribution of various components and assemblies in the frontal crash energy absorption is determined. Thickness of components with more remarkable contribution is increased to improve the occupant safety. Furthermore, effects of substituting the metallic bumper with one fabricated from GMT materials on the frontal crash beha...

This study aimed at indexing crash worthiness capability of 20 most frequently used car brands in Iran. Since rollover crashes are one of the most important crash types due to their high impact on crash severity, they were chosen as the case study of the current research. In this regard, the data of 42,118 rollover crashes of urban and rural roads of Iran which occurred from 2009 to 2012 was us...
