Hello ,
I'm trying to model the forces on a needle being inserted in a tissue. Needle tip penetrates the tissue surface and as it moves through the tissue, it experiences friction from needle-tissue interaction. Friction arises from the pressure exerted by surrounding tissue as it grips the needle. Assuming we have all the properties data for the tissue material, needle dimensions etc, how can we determine the pressure from the tissue ? [for friction force calculation]
