Damage modeling with UMAT

Submitted by Panos Efthymiadis on
UMAT

Dear all,

      I am using a Abaqus modeller with fortran subroutines. I have written a UMAT subroutine and now want to apply some damage initiation-evolution criteria. But I get the following error: a damage initiation property was used with a user material.

I wanted to apply the criteria externally from the subroutine.. How can I go through with this problem? I tried different criteria (stress and strain based) to check if it is a matter of the output variables... No result..

Rodney Hill Prize

Elsevier Limited has established a prize named The Rodney Hill Prize in Solid Mechanics. This prize, which consists of a plaque and a check for $25,000, is to be awarded in recognition of outstanding research in the field of solid mechanics. The prize is to be awarded every 4 years, to coincide with the quadrennial International Congress of Theoretical and Applied Mechanics (ICTAM). The first prize was awarded at ICTAM 2008 in Adelaide and the second will be awarded at the ICTAM 2012 in Beijing.

Who can provide a failure model and constants for Aluminium 6061-T6?

Submitted by RunQiang Chi on

Hi.

I am working on the simulations of impact. I have only found a set of constants for AL 6061-T6's JC failure model in the literatures. (D1=-0.77; D2=1.45; D3=-0.47; D4=0; D5=1.6) 

However, the simulation results using these constants were not good.

Who can do me a favour and kindly provide another  set of constants (D1~D5)? Or, may you recommend another failure model and constants for AL 6061-T6?

Thank you very much.
