    apply displacement instead of force

    In my model, when I apply the force/pressure, model becomes unstable. I know applied displacement controlled can solve this problem. However, how do I know the value of displacement should I apply. Can I check the reaction force to ensure the displacement that I apply being the same the...

    hyperfoam FEA?

    Hyperfoam is a kind of elastomeric material with very highly compressible. How to check this material can withstand incompressible which strain inexcess of 150% during service load. What parameter should I check and what precaution should I take? Thanks.

    Can we delete *.rec file?

    After the job completed, can we delete the *.rec or abaqus.rpy, or abaqus_read_step0 file in the working directory? Thanks again

    How to find .msg file?

    Hi Guy, I have some simple questions. Where can I find the .msg file? I can find only .dat and .inp files in my working directory. Where can I check the resultant applied loadings in my model after the (processing)job is done. Thanks. BTW, how can I change the scale factor for the...

    Fastners connection in FEA!

    Hi, I am the user of both abaqus and Pro/Mechanica. As fastner connections was introduced in the version 2.0 in pro/M. I found compared with abaqus, it is rather simple to make connection between two parts by screws or bolts, what you need to define is edges of the holes, materials, diameter of...

    What is the command in config.pro

    I want to have the config.win running all the times I open Pro/E. I put that file in the start working directory, but it does not load automatically. Anyone knows the comment in config.pro to setup the loading path for config.win? Thanks a lot.

    Pre-tension in bolts

    Anyone has experience in the modeling of the bolts connecting two parts? What is the difference if the pre-tension on the bolts is included or not? I mean, the stress and displacement for the two parts will be affected so much with the presence of the pre-tension? Thanks a lot.

    Any FEA books recommended?

    I have read many threads to discuss this topic already. These recommendations are based on the topics, such as contact mechanics, non-linear or etc. But, I can't find any book to discuss some topics, 1) how to apply the situable boundary conditions, loadings in order to simulate the real case...

    Any standard for low head bolts?

    Anyone knows any particular standard in ASME for the bolts, low head profiles, not the regular one. Thanks a lot.

    How much gap between parts in assembly?

    Hello all, I am working on the assembly with different parts. I know this is the contact nonlinear problem. What is the amount of the gap need to be in order to model the real case? I know the gap will strongly affect the contact pressure between parts. The problem is not press-fit, should I...
