Authors Abstract
Content
Most accident reconstructionists realize that valuable information about a collision can be obtained from evaluating light bulb filaments. However, few fully understand the scientific phenomenon involved, and little research has been conducted in recent years. This study presents an applicable representation of realistic automobile collisions. In addition, the study takes into account the effect of used/aged bulbs and determines how effective filament stretch analysis can be used and under what conditions such analysis should be avoided. An innovative duration sensitive light bulb acceleration apparatus was used to determine if a consistent threshold Delta V exists that can be used to assist in the determination of impact severity.
