I have a question that may pose some debate: I have a vehicle vs. bicycle crash. The impact was a blunt force impact.

Thank you for the timely reply. If I do not have access to these software programs, do you know of an actual list of formulas I can use to calculate values for b1 and then A and B? The formula used by IPTM is as follows: DeltaV= change in velocity b0= zero crush speed (in/sec) L= overall length of c...
