Hi All, I got a file generated from a CMM machine for measuring some par maters of drilled holes such as circularity and hole size, I also found that it measured perpendicularity (it shows PERP) so I assumed it is perpendicularity. my question is what is the unit usually used for measuring hole...

Hi All, I did some experiments and I used full factorial and fractional factorial as shown below: Test 1: 2 factors, 3 levels full factorial 3x3=9 points Test 2: 4 factors, 3 levels fractional factorial 18 points (High-Low and 2 for center points) I repeated each test 3 times in total. would...

Hi All, how can I represent the feed rate (mm/seconds) as a displacement boundary condition rather than a velocity boundary condition in Abaqus, I tried using U3 and constant amplitude but it seems I am missing something here. Cheers

Hi all, I have been trying to find the mechanical properties of the GLARE fiber metal laminates in order to use them in my 3d model in abaqus, I have managed to find all the S2 glass fiber mechanical properties except for the tensile and compression failure stress in third direction X3t and X3c...

if i modify the input file and then run it through abaqus CAE and then create a new job, the new input file created does not have the additional lines which I added before?? how can I avoid this problem

Hi trickstersson, sorry for the late reply, I have managed to get over this problem by using surface to surface contact and it worked fine for my models, I am modelling drilling process, but I think I should also learn how to do this in the way you described to me , I have tried many times...

I am trying to mount a circular clamping brackets made of aluminium around a drilling CNC machine spindle , the total weight of the clamping brackets is around 600 grams,I will perform some drilling tests but I am worried that the centrifugal forces made adding this weight on the spindle will...

hi Bill, thanks for the reply, I am doing a research and I want to cover as much as possible of the drilling parameters but I don't want to use any random cutting speeds and feed rates , I prefer to have a more realistic combinations of cutting speeds and feeds. Regards

Hi all, what are the recommended drilling parameters ( cutting speed and feed rates ) for drilling GLARE material. can I use similar drilling parameters used for Al2024 , any suggestions ?

I also got this message file : Abaqus 6.11-3 Begin Compiling Single Precision Abaqus/Explicit User Subroutines 7/9/2013 5:04:25 PM End Compiling Single Precision Abaqus/Explicit User Subroutines 7/9/2013 5:04:25 PM Begin Linking Single Precision Abaqus/Explicit User Subroutines 7/9/2013 5:04:25...

Hi all, I am using Abaqus 6.11-3 and Intel Fortran 11.1.065 and Microsoft visual studio 2008 When I run my subroutine with my model I get the following error message : Problem during linking - Single Precision Abaqus/Explicit User Subroutines. This error may be due to a mismatch in the...

Hi xwb , this is a copy of subroutine I am trying to fix using Microsoft visual studio 2008 Please feel free to make any comments on it Kind Regards http://files.engineering.com/getfile.aspx?folder=3ba55747-9178-4908-bf30-396e4f893b19&file=file.for

Hi xwb , thank you for the comments you mentioned the file was posted initially in one of the forums online and I took it from there ,I tried to fix it by myself but I couldn't , I have already put it inside a Microsoft visual studio 2008 file and I will post it here tomorrow morning. Thank...

Thank you all , I managed to fix the problem , all I needed to do is to select the edited input file and run it when I run the job.

I have a user subroutine which I found freely available online and I am trying to create a .for (FORTRAN file) out of it and use it with my models, I tried fixing it by removing the errors and warnings but I still get some , I have no experience with programming languages but I really need the...

Hi trickstersson , I tried what you mentioned but it did not work for me :( ,I will tell you what I did exactly: in the plate part I defined the following Set--> type : element then selected the whole plate and named it ERODE then I opened the input file and before *End Assembly I...

How can I run the modified job.inp file in Abaqus CAE , every time I make the change inside my input file and then I import the file into Abaqus , it keeps asking me to overwrite the current existing job file and when it does that the lines which I added in my job file are gone.

Hi All, I am trying to learn some Abaqus simulation about composite damage and subroutine writing , there is a source code file called uniFiber.for which I am trying to use to practice with it , I looked for it everywhere , all websites say that it can be downloaded from SIMULIA Answer 3123...

(where SURF1 is any name you choose to name internal surface and ERODE is an element set containing all the continuum elements of perforated part - this should be defined in Abaqus/CAE) Do you mean both SURF1 and ERODE should be defined in Abaqus/CAE or just ERODE ? Also when I submit the job...
