Disparity in Simple Shear solution in ABAQUS
Dear All,
We tried to simulate simple shear using ABAQUS and compared it with the analytical solution. To our surprise, even though the equivalent stress and strain matched perfectly, the component stress and strain had a large deviation between the semi analytical and ABAQUS methods. The zero components in the analytical model were calculated to be non-zero in the results of ABAQUS. This paradox could not be understood clearly as whether it is a case of software deficiency or conceptual error. A COMPLETE ANALYSIS OF THE PROBLEM IS ATTACHED AS A REPORT.
I have asked for technique support. Their answer was that my strain rate was incorrect for finite deformation. But I do not think so.
Could you have any thoughts? Thanks.
Regards,
Harry Wang

Re: disparity in simple shear
Dear Harry,
I'm also having the same prob in simple shear; for my case it's the comparison between rubber model in abaqus and analytical. Perhaps you can have a look at a paper about the simple shear (read the concluding remark):
Simple shearing of incompressible and slightly compressible isotropic nonlinearly elastic materials. C.O. Horgan & J.G Murphy. J. elasticity (2010) 98: 205-221
