Viscoelasticity Kelvin-voigt model in Abaqus

Hi all,

I'm trying to model kelvin-Voigt type material (response of it during time)

The equation is very basic : sigma*epsilon+d/dt epsilon*viscosity coefficient(eta)

i'm wondering how to impliment the viscous term eta in Pa.s (experimental results gave me the value) in my model.

The theory is very simple but i can't figure out how to do such thing in Abaqus.

I tried Pony type but i don't now how to calculate the coefficients..

 

Can you help me?

Abaqus - MISES stress as output variable

Hi,

 

I am doing a simulation in abaqus where pressure is applied over a rectangular solid model. I requested MISES output from one of the element where the pressure load is applied. My doubt is, " Is that possible to find the possible biggest model size above which the MISES stress will be constant ? ".

 

Boundary conditions are such a way that X and Z coordinates are totally constrained. the load is applied on the y-direction.

Electric analysis in abaqus

Hi,

I want to do an electro-mechanical analysis in abaqus. The specimen is a steel block of 50 x 50 x 20 mm with a groove/slot of 4 x 25 x 20 mm as shown in attached image.

I want to pass 20 amps current at location shown in red and then check the voltage drop at location shown in blue colour. Please can guide me the how to do this analysis in abaqus.

Thanks

Can we give the output as the input for the new analysis.....

Dear all,

I want to simulate the continuous forging operation in abaqus.

So after one forging operation, can i give the deformed shape as the input for the next cycle.

 

 

It would be kind of you to reply to me as soon as possible.

Thank You,

ABQcaeG.exe has stooped working

Hello everyone

I have AMD FX 4100 Quade-core processor, 3.61 GHz, and 8 GB DDR3 RAM, I hav windwos 7 64bit  ultimate installed in it.

When i installed Abaqus 6.9.1 or 6.10.1, it shows ABQcaeG.exe has stooped working. I tried different operating system in my PC, it shows the same error. I am not able to figure out what may be the problem. I am expecting something may be done with registry value. But I am not sure.  

Any one please help me.. due to this I am not able to sstart my project. I will be very thankful to you..

How to avoid the penetration in abaqus....

Hi,

I used abaqus 6.10 for analysing the an pressing opertion.

i gave the interation properties and other loading condition.

But, during the analysis, the die is penetrating inside the workpiece.

How can i overcome this.

 

With regards,

i need your help in working on modeling of my project in Abaqus.
im working on model of an Article.
the field of project is about underwater explosion.
This is the original article:
http://www.sciencedirect.com/science/article/pii/S0167844209000731

first i have to design the model of the article in abaqus.
as you see in article the model is a submarine hull.
i decided to create 3 parts : 1. dome end Semi-spherical 2. Cylinder  3. Stiffeners

abaqus/cae

question:

if we have dead load and live load in our modellinng and use riks step and we enter the dead load just through the densite....after the analysis ,which load must be multiply to LPF ?

abaqus noGUI problem?

hi everybody,

 I'm a fresh man in Abaqus. Recently, I find that  the command 'abaqus cae script=job.py' works very well, however, the command 'abaqus cae noGUI=job.py' doesn't work. But the the 'job.py' is exactly the same! By the way, the problem shown by abaqus is located in the output area, fieldfieldoutput and historyouput.

 Does anyone know the difference between them? 

Thank you in advance!

abaqus errors

hi dears

i have som problems in my project that should be simulated  with abaqus .

The
elements contained in element set ErrElemExcessDistortion-Step2 have distorted
excessively.


There
is only one excessively distorted element


The
ratio of deformation speed to wave speed exceeds 1.0000 in at least one
element. This usually indicates an error with the model definition. Additional
diagnostic information may be found in the message file.

Abaqus tire wear analysis

Hi all,

 

I am trying to complete the tire wear analysis example problem in the Abaqus user manual but I am having trouble with the input files. I have fetched them from the zip file using the fetch utility and I can import the first file (treadwear_axi.inp) in to Abaqus 6.9 but I am unsure how to continue as the other files do not appear to be complete.

Could someone please suggest to me the next steps to inport the remaining files and run the analysis.

Many Thanks

ABAQUS: I can't find the ErrElemMissingSection as defined in the error message of the aborted job.

Hi Guys,

I am facing the following error in the execution of a job in ABAQUS: 

'Error in job ModalTest_2: 27 elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection.

Error in job ModalTest_2: SECTION DEFINITIONS ARE MISSING OR INCORRECT FOR THE ELEMENTS INDICATED ABOVE. FURTHER PROCESSING OF THE INPUT FILE IS NOT POSSIBLE UNTIL THIS INPUT ERROR IS FIXED.'

Abaqus/Explicit memory usage


Hi all. I am running forming analysis on abaqus 6.10 on 64 bit platform with 8 gb of RAM. How can I give max memory usage for abaqus/explicit? There is a built in option for abaqus/implicit but for explicit there is no such option.

I want to allocate max amount of RAM for the analysis. Please help me with that.

analysis of RC cooling tower

Hi.

The topic of my thesis is about analysis of RC cooling tower under earthquake loading. The way of this analysis is FEM & for this analysis, I'm doing with "Abaqus" software.

 

I ask that this software can analysis this structures?

 and

 for modelling of the rebars of X-legs in this structure, what can I do?

 

Thanks.

Drawing 3D geometry in Abaqus CAE/Command

Choose a channel featured in the header of iMechanica: 
Free Tags: 

Dear All,

I am going to draw a 3-D model to be run in Abaqus. I would like to know how I can do that.

I find it is a little bit cumplicated to design the 3-D structure with certain curvatures in CAE. 

Could anyone tell any assisting softwares or approaches of designing the 3-D geometry in a simpler way for finite element analysis?

 

Many thanks,

Smeared Cracking Model in ABAQUS

Choose a channel featured in the header of iMechanica: 

I am trying to analyse a beam subject to elevated temperature using smeared cracking model for concrete. Its sequentially coupled thermal stress analysis. I am a newbie as far as ABAQUS is concerned. Can someone please help me out with the smeared cracking model. I am not able to figure the tension stiffening properties that I need to enter. Please help.

Modeling fatigue crack growth in abaqus using xfem

Hi

Dear all,

I am new to abaqus and I have to model a fatigue crack growth using xfem.

I have searched for a tutorial for that and I could not find anything useful. 

Does anybody know where can I find the tutorial or smth helpful?

tnx in advance,
