Influence of surface irregularities during rolling contact
Hi all,
A smooth cylinder in contact with a cylinder that is fitted with one of two irregularities: a 0.4 μm deep groove, or a 7 μm deep groove. the materials are hardened bearing steel and the 440C grade. how to calculate contact pressure distribution Hertzian pressure for contact with the grooved and smooth surface.
Looking for your valuable suggestions,directions.
which is a good book would give answer for the present problem?
Thanks in advance,
Rajesh
How to write an input ABAQUS file containing UMAT and USDFLD together
Hi everyone,
I am trying to model composite failure in abaqus. I used USDFLD to check different failure mode (fiber tension/compression, matrix tension/compression,..) based on available theory of failure. After checking the failure, if any element fails, the material property like stiffness will suddenly reduces to near zero. At this time i need to chnage material stiffness in UMAT and getting new stress distribution.
My problem is in the input file (inp file) how can I use both command for USDFLD and UMAT?
Here is a part of my input file:

IMECE 2011: Minisymposium on Multiphysics Simulations and Experiments for Solids
Dear Colleagues:
We would like to invite you to submit an abstract for the 2011 ASME
IMECE in Denver, to be held November 11-17, 2011. Our minisymposium
is on "Multiphysics Simulations for Solids", and is the
continuation of a very successful minisymposium held for the past 4 years
that have resulted in more than 50 presentations at the 2009 and 2010 IMECE conferences. This year's focus areas
are:
1.Multiphysics modeling, simulation and experiments of electromechanical materials and systems
