I'm using the fastener function in Mechanica. I don't think it deals
with clearance, and the stiffness is calculated based on material and
diameter... in this case 15mm and steel.
I am definitely thinking, after all you help, that it IS just a matter
of scale... see my earlier posts...
Interesting comment here about the shear load and friction. If I
calculate the required coefficient of static friction required for the
friction force developed by the tensile load to balance the shear load
it comes out to 0.419. Both parts are 80-55-06 cast iron and this
assembly is living in a cavity of automatic transmission fluid. I
wouldn't think the coefficient would be that high for these. Of course,
the fastener function doesn't have any "friction" adjustability... at
least as far as I know. Or does it???
Thanks...
