I have made a user element, UEL of a cohesive zone element. which is a 8 noded brick element with zero thickness. After solving models using this element I would like postprocess the model in abaqus CAE 6.10 in the way that I am able to:

Dear All,

I am running an axisymmetric model of a parabola tip on rigid surface contact under external load controlled by CLOAD. However, the CPRESS value outputed integraded over the annular areadoesnot equal to theexternal load inputed. The reaction force from the system does though.

I am suspecting that there is shaer component in the numbers given by CPRESS, but CSHEAR are all zero. Could anyone give me a hint on this problem.

Thanks a lot,

buckling of CFRP under combine axial compression and torsion loading.

hi,

I have to perform an non-linear buckling analysis over CFRP cylindrical shell in ansys. now i am little bit confuse how to perform this combined loading in ansys.in order to buckle some impurities (pertubation/imperfection ) must be included into the shell as this combine loading is purely in-plane loading case. this impurities i was including by performing a eigen value buckling during pure torsional loading and pure axial compression individually. but this is not much convinient during combine loading.

So my quries are

The Multiscale Modeling (MSM ) Consortium has been set up by a an interagency modeling and analysis group (IMAG ) comprised of staff from 17 NIH components, four NSF directorates, two Department of Energy (DOE) components, five Department of Defense (DOD) components, the National Aeronautics and Space Administration (NASA), the United States Department of Agriculture (USDA) and the United States Department of Veterans Administration(USDVA) to provide a forum for discussion on matters related to MSM research and
