Buckling analysis

    • Sandra Kvaternik Simonetti

      Hello!

      I have used Ansys Workbench for thermal buckling analysis of beam structures using shell elements. 

      Is it possible to model linear temperature rise along the beam length - on one edge of the beam temperature T1 is applied, and on the other edge, the temperature T2 is applied? I would like to know the critical buckling temperature for that case.

      I have used uniform temperature rise and linear temperature rise across the beam wall using Static structural connected to Eigenvalue buckling.

      Thank you,
      Sandra

      Hi
       
      One way is to run a thermal analysis with T1 and T2 on each end and couple that to a Static (this will transfer the temperatures over). The Static can then be as you said connected to a Buckling analysis.
      Alternatively, and perhaps easier, in the Static add a Thermal Condition load, and then use tabular data with variable equal to your length coordinate (say Z if it is along length or any dimension you need).
      All the best
