  1. material orientation for honeycomb modelling with /PROP/TYPE6

    Hi George, do you have new informations regarding my issue? best regards, H. Huebner
  2. material orientation for honeycomb modelling with /PROP/TYPE6

    Hello George, Can you please share your model with .h3d files?
  3. material orientation for honeycomb modelling with /PROP/TYPE6

    When i Isolate the core i get the same results as well. Do not understand why it works in your model. Did you Change anything in the model? Did you change the orientation by changing the skew? Can you please share your model with .h3d files?

    Hi George, how exactly did you Isolate the core? Did you delete all components accept of the core in the radioss file?
  5. material orientation for honeycomb modelling with /PROP/TYPE6

    Hi George, The shear modules are different in my model (G23=25; G13=40). So actually the shear stress results should be different if i Change the skew even if E11=E22. Do you have any idea why it does not work?
  6. material orientation for honeycomb modelling with /PROP/TYPE6

    This is the same material model, with E11=E22=1; G12=25; G23=40; The shear stress is direction dependent as you can see. Therefore a Change of the skew should Change the results. In the single element case it does, but in the main_Retainer_0000.rad model it does not.

  8. material orientation for honeycomb modelling with /PROP/TYPE6

    I checked it already in HyperCrash and HyperCrash takes it into acount. But i get the same results anyway if i change the skew. The right models skew is rotated 90° by the z-axis but the results are the same:

    Hello George, please find attached the model files main_Retainer_0001.rad MaterialDataBase.rad Retainer_0000.rad main_Retainer_0001.rad
  10. material orientation for honeycomb modelling with /PROP/TYPE6

    Hello George, Thanks for your reply. I've tried to assign the orientation using the vector base node and vector end node Option. In one case the local vector i defined corresponds to the global X axis and in the other case to the global Y axis. But the Problem still persists so i receive same results in both cases. Please find attached the .out files of both models Core_0000.out reverseCore_0000.out
  11. Im trying to model a solid honeycomb core with MAT28 and PROP6. I'm using a local coordinate System (/SKEW/FIX with Ip=0) to define material orientation. I tried to Change the local coordinate System but the solver always refers to the global coordinate System. A change of the local coordinate System does not affect a change of the material orientation therefore i'm not able to define the material orientation with a local coordinate system. Can anyone help me with this issue? Best regards
