Drucker stability
Drucker stability
(OP)
Hi,
i want calibrate a hyperelastic rubber in abaqus, i have experimental data and i want use Mooney rivlin and Yeoh.
But, also, i want check Drucker Stability?
can i do it?????
is there a internal tool in abaqus or i must create a subroutine, and in this case how?
thanks a lot

RE: Drucker stability
Also, there is a calibration utility built in in Abaqus/CAE. I recommend looking in to the documentation for more.

RE: Drucker stability
How can i do it with isigth?
For convex curve you intend in material calibration with the use of test data?

RE: Drucker stability
Assuming you are familiar with nonlinear continuum mechanics, then you could plot the strain energy potential against Green-Lagrange strains (E_ij) for the strain ranges of interest.
All of this said, you do NOT have to do it. Abaqus does it for you. Check the documentation.
