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...
