    Hole perpendicularity

    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...

    Analysis suggestions for my collected data

    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...

    how to represent the feed rate as displacement boundary condition

    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

    Looking for the cohesive material properties of the FM94 adhesive to be used in Abaqus

    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...

    internal surfaces - perforation problem

    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

    what are the recommended speeds for drilling GLARE

    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

    what are the recommended speeds for drilling GLARE

    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 ?

    Subroutine need fixing

    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...

    Modifying the input file

    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.

    internal surfaces - perforation problem

    (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...
