EDCRASH

EDCRASH (Engineering Dynamics Corporation Reconstruction of Accident Speeds on the Highway) is a reconstruction analysis of single- or two-vehicle accidents. The program determines the conditions of impact, including impact speed and delta-V, using information obtained from vehicle and accident site inspections.

For oblique collisions, the impact phase is anlayzed using the conservation of linear momentum; for collinear collisions, vehicle damage is used in conjunction with stiffness coefficients derived from crash tests. The impact-to-rest phase is analyzed using energy methods, with extension allowing for the effects of vehicle rotation and curved trajectory.
