How to draw the PDOF?

Side Impact CRASH Crush Stiffnesss coefficients - Driver's side vs passenger side
Q: Has anyone dealt with questions about using side stiffness values for a passenger side impact? While one would think that both sides are the same, it is a fact that the crash test data used for side stiffness values comes primarily from driver's side only crash tests.

Re: A Needle(slap) in a Haystack...aka Stuck Speedometer Reliability
Oct 2020A: Postings on INCR included the following references: I preface this list with the conclusion from a reference above... In general, the practice of representing a residual speedometer reading as that vehicle’s speed at impact is strongly cautioned against. Speedometers and Collision Reconst...

Re: What happens when a vehicle hits a pothole or rut at high speed?
A query about potholes came up and so i did an initial review of the pothole paper (SAE 2015-01-1572) and unfortunately it does not include any full-scale tests (see Summary/Conclusion 5) and an important missing element is what shape/size might cause de-beading/air-out? The study does include an im...
