    Cool XFEM simulation for 3D model. Is this a cohesive segment or LEFM approach?

    Hi! Just a bit of confused about the Max Principle Stress. The Young's modulus you input is 300e9 (300GPa), but why the MPS is only 100 (Pa)? Thanks!

    • @vineeth9295
      @vineeth9295  4 ปีที่แล้ว +1

      Good Observation Aoki Zyo , I checked the simulation and in that I used Maximum Principal stress as the failure criteria with value as 100 Pa and keeping Youngs Modulus of steel as 200Gpa. The MPS value should have been kept as the yield stress of the steel somewhere around I think 250 Mpa according to MPS criterion. The value 100 Pa was assigned so that crack could propagate easily.

    Hi Vineeth. Do you know how to model the permeability?

    • @vineeth9295
      @vineeth9295  3 ปีที่แล้ว

      I am not sure but Permeability means ability of fluids to pass through. So will the usage of membrane element help?
      Edit: Just guessing

    Thanks for sharing this, have you done smeared crack model in Abaqus? or know where I can find full detailed model for this?

    • @vineeth9295
      @vineeth9295  4 ปีที่แล้ว

      🙋‍♂I think you can find research papers of smeared crack model and based on that you can perform the simulation🙌

    Hello Vineeth! can i use this same process to make a crack in a concrete cube? I mean without fixing one side

      You have to give atleast one dirichlet boundary condition

      As you are talking about tube the length will be large, so try to use plane strain condition and check

      Hello@@vineeth9295, thank you very much for this quick reply, It is not happening, idk why. If I carefully watch your video at 3:38, you assigned only to the cantilever beam, if I am not mistaken but did not to any crack plane. Even if I am doing a manually it is asking for thickness, with any thickness it is giving an error as 'Too many attempts made for this increment.
