Hi Guy's, I'm starting a project to explore the physics of hysteresis friction between two surfaces.
One flat metal surface is considered to have zero compressibility but does have grooves interrupting the sliding action.
The second material (organic elastomeric compound) also having a flat surface, with a certain degree of compressibility (yet to be determined) and a known coefficient of friction when applied to a flat uninterrupted surface.
I have plenty of data when applied to two flat uninterrupted surfaces.
It's the introduction or new consideration for surface interruptions that I'm exploring direction on. I understand there will be a combination of ploughing friction (shear) and hysteresis friction (deformation). I'm wishing to calculate the addition forces required to overcome this unknown resistance.
Any advise would be appreciated to accelerate the discovery process. Thank you.
