ABAQUS

Dear Researchers,

I am trying to find out which was the first ABAQUS version, wchich includes the hyperfoam material model. I haven't found any version history about this. Could someone tell me the very first version of ABAQUS in which the hyperfoam model was included?

Thank You!

Kind Regards,

Is it possible to model and do the thermal analysis of a thermosiphon loop using ABAQUS.

How to define JOULE HEAT FRACTION in ABAQUS as a function of temperature? Thank you!

Hi every body,

I'm tring to make a beam by using beam elements in Abaqus like this:

Hello everyone,
 
I am working on textile composites. I have to assign local material orientation for the fibers. I have come across *ORIENT  subroutine in abaqus. But I am quite new to user subroutines. Is there any other way in which I can assign local material orientation to the fibers?
The fiber layout is such  that it has linear as well as sine part. Can anyone give some idea on how to create *ORIENT for such fibers?

Thanks

I calculated an example of unaxial tension using GTN model offered by Abaqus. I followed all the instructions found in CAE User's and Analysis User's manual in Abaqus documentation. No error or warning was issued but the result seemed ridiculous, since VVF, VVFG and VVFN keeped 0 throughout the process while equivalent plastic strain keeped increasing(which showed the material had come into plastic deformation). I don't know what went wrong, looking forward to you reply.

Hi,

  I want to simulate Ice failure simulation in abaqus. In my problem, ice is deposited between 2 components.

  While I am trying to move one compoents, the ice is restricting the movement of the components. Now I want to find out the force at which the ice starts to failure .

  any methods are available n abaqus., Plz let me know if any body knows abt this kind of simulation.

Thanks in advance

Hello,

I have to do a FEA regarding impact damage and delamination propagation in a CFRP specimen.

I have to do this using cohesive element in order to see the propagation of the delamination front in the material.

My problem is that I don't know how to do this in Abaqus.

I'll better explain: I can use this software but is the first time approching composite behavior and I really don't know how to model that.

I am new in using abaqus, please can any one help me with tutorials, book or anything that guide me on how to simulate failure and damage progressive in composite materials using abaqus.

Thanks you all 

Hi every one,

                   Does Any one know the difference between Max. Principal values and Max.Principal(Abs) values in Abaqus ? I searched from there manual..but they have not mentioned in there manual too..could you please let me know the difference between those two parameters? Thank you very much.

Hi,

Hi

I have a simple question. How could I model associative Tresca plasticity in ABAQUS?

 I use Property module: material editor: Mechanical:Plasticity:Mohr Coulomb Plasticity

I know that In the case (friction angle=0) of  the Mohr-Coulomb model reduces to the pressure-independent Tresca model with a perfectly hexagonal deviatoric section. 

Hi all,

     I am looking for some reference on procedures for applying  PBC in  abaqus? I coud find some journal articles for the equation, but I am unaware of applying this into Abaqus under displacement laoding conditions..

any help in this regard would be appreciated greatly..

Thanks,

Bernad
