Use UMAT if you use Abaqus Standard, VUMAT for explicit

Hi Van

As Dr. Baeker mentioned, use the UMAT.

Dear Dr. Baeker,

I have used ABAQUS/EXPLICIT already.

But I still wonder that if VUMAT can run well with a material constitutive that has lots of iterations?

Thank you very much,

Bac.

hi Van

Both UMAT and VUMAT can work well even there are many iterations invovled in material consitutive. I used VUMAT with inelastic material modeling of concrete beam and joints

good luck

Hi Mr. Raafat,
