The equation that is expressed in your attachment gives an equation for how delta sigma depends on delta strain. Have you tried to expand the terms and then collect terms in order to get each term of the Jacobian? I would think that it should be possible to get the necessary terms that way.

please send me that code i have got some problem for the same.
Thanks
