Hi to all,

I was reading a paper about calculation of ALLCD/ALLIE in Abaqus Explicit which is called Hysteresis Ratio (HR).

Seams that this quantity should be constant since it is function of Rolling Resistance force in a tyre and it cannot be time dependent.

Once I run Abaqus explicit simulation of tyre in rolling condition with PRF model I see that both ALLCD and ALLIE increase with time so also ALLCD/ALLIE varying over time. So my question is:Â

How can I use this formula if it's time dependent? How can I get a constant value?

I also share here the paper where I have found this formula

Thanks a lot

Best
