Dear imechanica Members,

I want to make a comparison between the results of a calculation of unit cell model and Gurson but I have a little problem on the triaxiality.

How to use the Riks algorithm in AbaqusCAE that the triaxiality remains constant during the loading of a unit cell?

Thank you for your help.

Best regards

Hi

The question is coupling the Gurson model with the crack propagation on a CCP specimen with Abaqus. Then a study of the influence of parameters of the Gurson model J-intgrale  And deduct the best set  of the parameters with we can adjust the JR curve computed on the experimental curve
