add the convergence criterion, the method is :
...
1. calculate the L2 norm of the residual of all the stress points
2. store the relative errors of the L2 norm
3. if the standard deviation of the relative errors of last five fittings is less than 0.05, that it is considered that the relative errors is stabilized, so the fitting is finished.
