In reply to Define the problem

Dear Kishan,

thank you for answering. I'm working on a thermo-chemical model that involve the polymerization of a resin. This phenomenon is exothermic and the heat generation depends from both temperature and degree of cure. Whereby I need to use the values of the degree of cure in each element. I thought to use an external file .txt from which the program can read in each iteration the value of the degree of cure and in which it can update those values at the end of the iteration. I thought to use UEXTERNALDB for this task. My model uses also other subroutine (HETVAL, USDFLD, UMAT, UEXPAN).

My problem is that I cannot find out how to call UEXTERNALDB subroutine (for example if I need to call the USDFLD sub I write in the .inp file the comand "*User Defined Field"). I hope that my question is clearer.

Thank you again.

Dear Fausto,

I have some experience with this subroutine but I am not able to understand what exactly you want to do.

Please define the problem.

Elaborate on the job

In reply to University of California Merced - Post Doc and Grad Student Openings

Dear Ashlie,

I am interested in this position.  I have just finished my Ph.D in the field of Computational Chemistry. Could you furher elaborate on the topic for adsorbates on the metallic surfaces ? 

I do not have any solution

In reply to XFEM ABAQUS- Different "K" for different mesh sizes

I do not have any solution for you. I read in different publications that in contrast to the assumption of a completely indepence of the mesh density, there is a explicit dependency on it.
How much do the solutions differ?

In reply to How to define initial stiffness matrix for cohesive elements in ABAQUS

Hi,

when you are using cohesive elements with traction-seperation law (not continum approach), pay attention that the stiffness parameters no longer have physical meaning. I mean you cannot use exactly young moduli of adhesive material , but a rule of thumb is to divide it by the cohesive element thickness. anyway, stiffness here is a penalty stiffness i.e you can choose it freely as long as your model converge and more precisely your results correlate with experimetnal results if you have.

for more information feel free to write to AbaqusSite@gmail.com

Best,

Mohammad

Nice Work.

In reply to Strain gradient plasticity modeling of hydrogen diffusion to the crack tip

It is a very nice paper. GNDs are important in explaining hydrogen emebrittlement mechanisms. Such strain gradient models can be further developed to include fracture mechanics based on total hydrogen concentration.

I have been working on the same problem but I have a long way to go.
