    Hi Professor, thanks for the useful lectures.
    You mentioned doing a couple of problems at the end of the video, but I couldn't find them online, it was the same for isotropic elasticity lecture.
    Are the problems and examples available online?

    would you be able to guide me on how to derive a stiffness matrix of an orthotropic beam element?

    Thank you Professor.
    You explain clearly and easily.
    But, do you have an explanation of strain energy density in anisotropic materials ?
    anyway, thank you Professor

    The quality of the content is very nice, the way how you teach is also very nice, but technically unpleasant to watch. I always need to find a frame that you didn't cover what is written on the board. There are many easy solutions for it. I know this is a free course and no right to complain but I just wanted to drop a feedback to here in the perspective of a student. Thanks, Cheers!

      +Prathamesh K Nye's little book is your friend. I think your answer is 6 - I don't have Nye to hand but quick googling suggest 6 - see www.iaeng.org/IJAM/issues_v42/issue_3/IJAM_42_3_10.pdf and link.springer.com/chapter/10.1007%2F978-3-0348-9229-2_12#page-1.

    Thanks for your explanations. I wrote to just mention a typo in your formulations. When you wrote the relation between stress and strain tensors in terms of the compliance tensor at time 3:30, you forgot to modify the indices and you wrote on the board S_ijkl \sigma_ij = \epsilon_kl instead of S_ijkl \sigma_kl = \epsilon_ij. Although this formulation is correct for hyperelastic materials having the symmetry S_ijkl=S_klij, at that time of lecture you talk about the most general form of C and S tensors and I think you should add a note to your video.
