    Hi Jerry,

     

    Refer to the below tutorials:

    Hi

    I need full tube analyze & also for Buckling of a Tube using pipe Mesh

    1)how bring file from solid works to hyper Mesh?

    2) how change boundary condition for full tube or pipe( symmetric)?

    3) for other shape or material how apply conditions?

    4) the other structurer inside pipe (composite ) and analyze together?

    thank

    Hi,

    1). You can import the file in HyperMesh. Users can import  IGES, SolidWorks and STEP file formats.

    import.PNG

     

    2). From Utility Menu, BCs Manager can be selected and users can assign the required boundary conditions.

     

    3). For any shape we can apply the BCs.

     

    4).Can you please elaborate on your project?.

     

    I recommend you to go through https://altairuniversity.com/learning-library/modeling-and-analysis-of-honeycomb-impact-attenuator/ which is a similar tutorial that shows Modeling and Analysis of Honeycomb Impact Attenuator.

    Hi

    1) I try to change  shape of  'RD-3030: Buckling of a Tube using Half Tube Mesh'  with pipe.

    the problem is 'Step 6:  Define boundary condition representing symmetry'.

    please run this file.and why  result go to hyper mesh again?

    After solve in this shape ,I will try to add other shape inside the pipe & solve again.(honeycomb & three ...)

    2) how to take report Graph of FORCE-DISPLACEMENT for 'RD-3030: Buckling of a Tube using Half Tube Mesh'?

    Hi,

    Please try running the file attached.

    You can create Force vs Displacement graph in HyperGrpah using Cross-plot option. Please check the below post which shows the same,

    Hi

    Thank's for your file.

    for take this result like pic and how apply the tube subjected to quasi-static axial compression?

    The result of this loading become pic 5.

    thank for your interesting

    Hi,

    We have a similar tutorial in the Help menu, RD-3530: Buckling of a Tube using Half Tube Mesh and the same tutorial is attached along with the model file for your reference and practice.
