    Dr. Hedegaard, I cannot express how thankful I am that you have uploaded such a wonderful tutorial series for the public. I never learned any FEA softwares besides ABAQUS at UT Austin during my master's and I often felt disadvantaged in job hunts. Again, these lectures are amazing and I am thankful that you decided to share your passion.

      You are most welcome! I first learned FEA using ABAQUS. Each has their benefits, but it's good to be flexible.

    Thank you so much doctor
    I work on structural in Babol nooshirvani university of technology in iran, your video is really great
    Have a good day

    thank you so much for your comprehensive lesson, I was wondering if the large deformation can be done on static analysis with a imperfection model?, much appreciated your answer.

      Honestly, I haven't tried it, but I don't see why it wouldn't work (famous last words of many FEA practitioners). A quick search turned this up... it this what you are looking for?

    Greetings Prof. H i have a question how the axial load caused the end moment to become almost Zero . what i understand is that the applied axial load should have increased the End moment as the deformation of the tip is upward which will cause an additional moment in the same direction

      I assume you mean the moment at the fixed end on the left? The applied axial force is pointing to the right (putting the cantilever into tension), but the concentrated moment at the right end acts counterclockwise. To find the moment at the fixed end, consider the summation of moments about this left fixed end. The axial force times its moment arm (deflecting upwards) acts clockwise, thereby cancelling out a considerable amount of the concentrated counterclockwise moment. That the resulting moment was near zero was an accident, but in general, this tensile force will reduce that left end moment while a compressive force would have increased this left end moment.
