    PATRAn Group Command

    The 'Utilities' section is free, and all the elements are installed as part of the main installation of Patran.... However, the 'Utilities' menu has to be activated after installation by the user. Alot of the features are incredibly useful, but are not supported (as such) by MSC, which I think...

    Patran BEAM and CAE Solid Modelling

    Thanks for the reply - I'm pretty sure the beam library is different, as that's always been available even without the additional licenses. My understanding is the 'BEAM' module is a visualisation tool that allows stresses around a beam element to displayed in a more meaningful way, by plotting...

    Patran BEAM and CAE Solid Modelling

    Its probably a bit of a 'numpty' question, but.... My company has just bought licenses for the 'BEAM' and 'CAE Solid Modeling' utilites for Patran, the problem being I don't know where to find these features within Patran to be able to test if the licenses are working! Are there extra bits of...

    Welding distortion simulation

    You might want to have a look through this on-line thesis, which studies how to simulate post-weld stresses and deformations with ABAQUS by physically modelling the wedling operation. I found it a good starting point for determining the practical issues associated with this type of simulation...

    Solidworks Integration

    Phoenix221, Depends what you mean by integration... I've only ever used Solidworks as a quick way for generating 3D geometry for meshing in Patran. If that's all you want to do, then saving the Solidworks model as a parasolid (.xmt) and importing this parasolid into Patran has always been a...

    *NODE PRINT v6.4 and 6.2

    smg2, On the ABAQUS website, there is a known bug listed on the status reports as error number V64_1808, which describes your problem pretty much to the letter. (A copy of the report message is shown below) ============================================ The output variables hydrostatic...

    Resin Infusion Info (the basics) wanted

    Hangglide, Try the very helpful bunch at the Advance Composites Manufacturing Centre at Plymouth University (www.plymouth.ac.uk). They have a vast experience of resin infusion technology, working both as an academic research department and as a consultancy to range commercial companies. The...

    Modeling welding using FEA

    Hi Brad, Dont know if this is in the links suggested by Lars-erik, but this link... http://www.stud.ntnu.no/~artem/welding.htm ..has been very useful to me for modelling the welding process, especially using ABAQUS. Example decks are included so you should be able to quickly build a model...

    abaqus cae 6.3

    I could be barking up the wrong tree completely, but I vaguely remember seeing an 'abaqus update' command in the release notes for 6.3, which I believe is used to transform the odb file from the old format to the new..... I haven;t got the manuals to hand to check this though... sorry if it...

    composite where the matrx and fiber are the same material

    I dont think the carbon/carbon composites used in high performance breaks are the same thing. One of the processes by which the C/C are made is to make a carbon/polymer laminate as 'normal' with the required layup, then heat the whole lot up in controlled conditions to carbonise the polymer...

    materials data on the net

    www.matls.com and www.matweb.com are one-in-the-same site now. All the old info available at matls is availble free at matweb, but if you want 'advanced features' then, yes, you do have to pay a subscription. GJS

    transverse shear stress distribution in composite laminates??

    Kevin, If you are defining the SOLID SECTION with TYPE=COMPOSITE, I dont believe it will make any difference how many elements you put through the thickness. It would appear that ABAQUS applies the TYPE=COMPOSITE according to classical laminate theory, and therfore assumes no shear transfer...

    transverse shear stress distribution in composite laminates??

    All, I think vonleuke is heading towards the crux of the problem here..... Using shell elements appears to be fine with type=composite, but the in-plane stresses my be slightly off.... Using solid elements with type=composites gives shear stress representation no better than a hand calc, but...

    Open FE-System for transient simulations (thermal+structural)

    Toothroot, Think I've post this site on another thread, but.. http://www.stud.ntnu.no/~artem/CHAPTER_I.pdf http://www.stud.ntnu.no/~artem/CHAPTER_II.pdf etc is worth a look as it provides sample ABAQUS decks of the code used in this chaps PhD. In ABAQUS the methodology for adding/removing...

    Open FE-System for transient simulations (thermal+structural)

    Toothroot, Prex is right.... sounds like your trying to do an analysis of a welding process, or something similar, with metal added to the weld pool as the heat source moves along. Most codes should be able to accomadate this - I've personally done somethign similar with ABAQUS, using the...
