In reply to Hi, spacetank

Dear Mr. Zidane611,

 

I saw your email here in this blog. I am also working with the same model and i am wondering to prepare a similar UMAT in a proper way.

 

In this case may I ask you please send me your UMAT please. My email is: a.nazarinezhad@gmail.com

 

It would be great help for me.

 

Thanks in advance and hope to hear from your side.

 

Greetings,

Hassan

New article: Generating polydisperse periodic RVEs containing ellipsoidal particles (part 1) http://www.parresianz.com/r/periodic-rve-with-ellipsoids/

I'll post the rest on the series on this comment thread because my articles are not showing up on the imechanica RSS feed.

In reply to Using Noise to Control Micromechanical & Macromechanical Systems

Thanks for sharing this.  I confess I am driven myself to study non-linear dynamics . Since we are studying also with Prof. Hoffmann similar systems (but we hadn't been considering the case of noise), I was wondering if you think your concepts are useful also for our systems (see 2 papers below), and we could perhaps take a closer look at each other's work.

In reply to nonlinear finite element software developer

Dear Professor,

I am Ashutosh Mishra having PhD in Mechanical Engineering and expertise in developing UMAT codes for Non linear cyclic behavior of hardening material. I want to work in the field of development of solid models and constitutive relations for behavior prediction of advanced materials.Can you please let me know whether I can apply for the position as I am from India?The link of one of my journal paper is provided for your reference.

In reply to ABAQUS example 3.1.1

I also wanted to get this manual into my hands. The german Abaqus HQ forwarded to me an e-mail from Abaqus World HQ:

"The bench mark problem is simply a clone of the first example problems in the second volume of TEXVISC user's manual. Besides the example problems, the manual only describes how to use the program. There is nothing noteworthy to make a copy. TEXVISC is a 2D finite element program for thermal and mechanical analysis."

So, forget it.

 

It is bizarre to declare a simulation correct simply on the grounds that some other FE program is declared correct.

 

Consult the forum.

ABAQUS example 3.1.1

Tue, 2017-11-07 11:18

In reply to Look up the BAQUS example 2.1

Dear Sir;

I have read the example you mentioned and it does explain how to convert certain data available for UMAT to ABAQUS input data but it does not give information on finding bulk moduli k(i)p, I have searched on different forums and what I have found is that if Poisson's ratio is 0.49~0.5 the k(i)p values are zero (not mentioned) which is true for the example listed. but if the Poisson's ratio is not within this range then how do we calculate k(i)p from conversion from above-mentioned data. Further, I have tried searching for the reference listed in the example "Collingwood et al. (1985)" but I am unable to find it. Could you please kindly provide guidance in this matter. thanking you in advance.

 

Best Regards;

Asim Gillani
