![]() ![]() The fundamentals of physics and mechanics are essential to the reconstruction of a vehicle collision. Scientifically accurate visualizations can be visually appealing court admissible additions to an expert witness’s presentation and prove to be invaluable in accurately explaining the events of a car accident. Biomechanical simulation can take the 3-dimensional dynamics from a vehicle impact simulation to predict injury mechanisms and occupant kinematics within the moving vehicle. The dynamics of a simulation such as these can be used as input to a full-fledged visualization effort or as input to a biomechanical simulation. Both methods are scientifically accurate and rely on physics to determine the resulting motion of vehicles. HVE is an alternative that precisely interprets the impulse duration and damage profile to capture the dynamic forces during a collision. ![]() Virtual Crash 4 is an industry standard in forensic engineering capable of rapidly testing collision scenarios using the impulse-momentum calculation method. Using virtual crash methods is a validated way to enrich an accident reconstruction and deliver a visual aid to better explain the events of a car accident.
