Re: What is the CRASH Energy Correction Factor (ECF)?

Q: In this ECF thread you mention "Looking at the Brach book Table 6.2, the listing for the RICSAC staged collision analysis, the value for MU for identical impacts varies arbitrarily" and also present values for RICSAC 9 from the book in Figure 7.14, p 145 and Figure 7.13, p 142. I currently do no...

Can CRASH calculate accurate Delta V ranges for low impact collisions?

Q: Can CRASH or CRASH3 calculate accurate Delta V ranges for low impact collisions (e.g. < 5 mph). I think I read somewhere that CRASH was designed more for cases >20mph with crush at least 2-4’’ A: CRASH is not good for low speed collisions. Why? Because the crush coefficients for CRASH are based o...
