Crash tests of vehicles by striking deformable barriers are specified by Government programs such as FMVSS 214, FMVSS 301 and the Side Impact New Car Assessment Program (SINCAP). Such tests result in both crash partners absorbing crush energy and moving after separation. Compared with studying fixed rigid barrier crash tests, the analysis of the energy-absorbing behavior of the vehicle side (or rear) structure is much more involved. Described in this paper is a methodology by which analysts can use such crash tests to determine the side structure stiffness characteristics for the specific struck vehicle. Such vehicle-specific information allows the calculation of the crush energy for the particular side-struck vehicle during an actual collision – a key step in the reconstruction of that crash.

Thanks to years of research and development by vehicle manufacturers, suppliers, legislation, and the entire safety community, the side airbag has become a critical safety device to reduce injury and save lives. This new collection of technical research highlights the progression of these essential safety features, providing a complete and thorough perspective through the analysis of both early patents and recent side airbag system developments. Advances in Side Airbag Systems begins with an introduction by editor Donald E. Struble, chronicling the progress made since the mid-1980s in offering improved side impact protection to the motoring public. Authored by leading experts in their respective fields, this book features a comprehensive collection of 26 landmark technical papers. Its scope includes not only thorax airbags, but other inflatable devices designed for side impacts and rollovers.

CRASH3 plays an important role in the development of accident data files, and in addition it is often used for reconstructing specific accidents. Had it been intended from the outset for this latter purpose, its development may have progressed along slightly different lines. It is now appropriate to examine the use of CRASH3 in specific accidents, the use of available crash test data, and the nature of the likely CRASH3 user. Suitably accounted for, all these factors would have a significant influence on the design of accident reconstruction algorithms, including any contemplated revisions of CRASH3. Such considerations are the subject of this paper.
