Error using Neo-hookean in abaqus

Submitted by Jaswanth_kumar on

Hi everyone,

I am trying to solve a problem of twisting a hyperelastic material(compressible neo-hookean) in abaqus. 

The problem has been taken from 10.12.5 TWISTING COLUMN in the textbook NONLINEAR SOLID MECHANICS FOR FINITE ELEMENT ANALYSIS: STATICS (Javier Bonet,Antonio J. Gil,Richard D.Wood).

Lamda and mu are given as 100 each, so I have calculated the Neo-hookean coefficients for abaqus which came out to be C10=50 and D1=0.012

I am using abaqus static-general with time steps of 

*Step, name=Step-1, nlgeom=YES, inc=10000
