Hi everyone
I am looking for experimental data in tensile or compression test for al2024-t3 at different temperature (100-450C) and different strain rate (1-10-100)(specially 10s-1)
I know there are some constitutive equations like johnson Cook or Zener Hollomon for estimation flow stress. but I...

Hi to all
have you ever seen this event? I observed it many times. when I want to simulate a rotating body which is deformable and comes into contact with another deformable-body, this problem appears. for example, when we simulate friction stir welding, during the process ( when we animate it)...

Hello to all,
I am modeling a rolling ball onto the surface using ANSYS Mechanical APDL. I modeled a ball far from 1mm from the plate then I applied displacement in order to the ball comes in contact. but before the ball detects the surface I see compress stress on the plate. I used these...

Hi asder
I think I found out the solution to cope with this challenge. so I wanna share it with you and other members
for the problem as follows:
assume that we have A plate at fist it was loaded to P1 (MORE THAN YIELD STRESS) then unloading to estimate residual stress. at the second it will...
Hello to all
Assume that we have two welded plates(the welding process already has been simulated ). now after cooling the plates , the new simulation or new analysis ( for example rolling) has to be done on these welded plates. accordingly residual stress and displacement should be resorted...
Hi
I have accessibility to high speed computer ( CPU=24cores and RAM=32GB). I adjusted ansys mechnical apdl product launcher as follows:
high performance computing setup-Type performance computing-used shared memory parallel(SMP)-number of processor=20
when I run the simulation and check task...
Dear AnPham
I checked it many times. as long as I import mentioned material property on the sample , every thing is ok and it works but as soon as I change it with other material unfortunately... it dos not work, it would be nice of you if take a glance to the codes that I uploaded in above...
Dear ANPham
thanks alot for your response. if you pay attention to my first post, I already mentioned the same link that you put in your post:
https://www.sharcnet.ca/Software/Ansys/17.0/en-us/help/ans_tec/tecfricstir.html
in this sample simulation was done for stainless steel 304L.
the link you...
hi to all
one of the best element to simulation with ALE ( arbitrary eulerian lagrangian)capability is solid 164. this element is available at ANSYS-LSDYNA. it has three DOF (ux,uy,uz). If we want to execute couple analysis (structural and thermal) like FSW ( friction stir welding) using this...
Dear friend
first of all I am so gratitude for your prompt and valuable answer. I should add that I derived and obtained many required parameters by citing articles and surfed in the handbooks....nonetheless by citing the sample and read it carefully I realized some imported parameters hadn't...
Hello to all
I am trying to simulate FSW using ansys mechanical apdl. there is a useful sample which was provided by ANSYS. you can find it at this address: https://www.sharcnet.ca/Software/Ansys/17.0/en-us/help/ans_tec/tecfricstir.html
I executed the sample step by step (for stainless steel...
Hi to all
My question is how to use inisitate command:
Assume we have 3parts. part1=plate1 , part2=tool2, part3=tool3. If we run an analysis using part1 and part2 .afterwards we want to run subsequent analysis between the same part ( part1) and part3. is it possible we write stress and strain...
I think non linear adaptive meshing is different from than Rezoning.meanwhile I told I wanna to model fsw statically till I arrive high penetration (at the plunge stage initially).
in the NLADM for 3d problem I have to use solid 285 which tetrahedral shape and four nodes is available for it...
