Re: WHY Use Simulation to “Test and Refine” Traditional Crash Reconstruction Results
Here are the redacted conclusions from our initial report to which the pc-crash expert wrote the aforementioned rebuttal report: and note line feeds added for readability SUMMARY AND CONCLUSIONS The PC-CRASH program includes a simplifying assumption of an instantaneous exchange of momentum. In real ...

Re: Why We Call It The James Bond Spiral Jump by McHenry
March 2024: Interesting coincidence. Earlier this year we were contacted by Chris Distin who's written a book on the movie with the stunt And the interesting coincidence: From the book a few items: The jump was filmed on the 1st of June 1974 , the 31st day of movie production. The patent had been a...

Re: The Effects of Friction on EDRs and DeltaV
March 2024, added mention and link For restitution effects, please see Effects of Restitution on the Application of Crush Coefficients for details on effects of restitution, which "reduces the residual deformation while increasing the total impact speed change". In this forum topic, we foc...

Re: What Speed should I Use to Calculate CRASH3 A&B Coeff?
Q: The argument behind the idea that we're getting to dV from damage and stiffness (and, of course, BEV) made me hesitate...maybe I read stuff wrong before and it IS dV we should be using. But, by my way of thinking, if I work it all the way back to Emori, for example, the input was always the spee...
