Solving Reynolds equation (EHL problem)
I'm working on the numerical solution of the mixed problem in lubricated contacts. Does anyone know if the lubricant equation (Reynolds one) was never solved for film thickness instead of pressure (like actually is done with MGMI techniques) in some pubblication?
Natural frequencies and mode shapes of rotordynamics

I would be gratefull in advance if you send me an illustrative examples about how to find out the natural frequencies and mode shape of rotor-bearing system by using abaqus.
What is the Shore A hardness used for?

The Shore A and D hardness tests are widely used by the rubber industry. However, I'm not sure what practical use these numbers can be put to during design. My current feeling is that Shore hardness numbers can at best give you a feel for the texture of the rubber - a Shore A value of 5 = gummy bear texture, Shore A = 40 implies erasure texture etc.
Can someone explain how Shore hardness values can be used in the design of mechanical components made of rubber?
Thanks in advance,
