GTN Model

Submitted by Mohamed H.Miloud on

hello

I identified a set of parameters of the Gurson model. How to use these parameters to simulate the propagation of a crack in a CT specimen?. In another way how to simulate the propagation of a crack with the GTN model?

thanks!

Tiaxiality in unit cell calculation

micromechanics and cell calculation

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

Effect of Gurson model parameters on the J integral for a CCP specimen with Abaqus

Submitted by Mohamed H.Miloud on

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
