  Thanks for the dissemination. There is something I would like to ask. Why did you use homogenous solid section definition instead of composite solid section definition? Thanks in advance.

  3D solid element method is NOT recommended. Instead, continuum shell element should always be used. This video is very misleading.

  No. I used both of them compared with experimental case. it is correct

  @@turanturan2831 I think you did not get the point. For this very simple case, you can use both methods. But for a complex composite structure, you need to map your mesh to different ply zones and continuum shell section is the correct method.

  Nothing should always be used. There is always a tradeoff between accuracy and costs. I watched your video. You used continuum shell in the wrong way. I don't think you really understand the mechanics.

  Depending on the stress state of interest solid or shell can be used. It is the user's responsibility to refer the user manual and define which element type is more suitable for the considered physical problem.

  sir, i wanna ask you, how to check cracking in model?

  @danielbadel12264 жыл бұрын

  Hi Mr Imam, from the model developed by Mr Luke we cannot see that, if you're interested in model damage initiation and propagation Abaqus CAE have the Hashin criteria installed by default only for 2D elements (conventional and continuum shell elements mostly used). Otherwise you can check the failure damage indexes from Tsai Wu and Tsai Hill criteria only by requesting their outputs however this only will indicate a damage location and not the type of damage itself. If you want to develop a more accurate modelling using 3D elements you have to develop your own material model following the Abaqus subroutine option VUMAT and asigning a initiation and propagation damage. I hope this can help you out. DB

  great learning from this video. I have a question here: Does changing material orientation to 45 or 90 implies fiber orientation also changes to 45 or 90 degrees?

  By changing the orientation of the materiel you are changing the fiber orientation
