Very nice video. Well done. Could you make a video showing an example of the final partial derivative? You have shown a relation between stress variation and strain variation. There is a double contracted product n : delta strain and trace (delta strain). How to perform these derivatives? Do I carry out the operation first and then apply the partial derivative ?Many thanks!
hi, how the plastic properties of wood are described in abaqus, Can you help or guide me on this? I can't find data or an example, I can't test it, I need to analyze in abaqus.
I have compared the final Tangential stiffness at 7:31 with the one in the Section 5.6.2 of the book "Nonlinear Finite Elements for Continua and Structures, 2nd Edition" written by Ted Belytschko. The conclusion is that the Q and R are slightly different, but the Tangential stiffness at 7:31 shows better convergence than Ted Belytschko's one.
For plane strain and axisymmetric conditions the relations and coding are the same just the number of stress and strain components are 4. But for plane stress condition the relations are a bit different.

This is amazing, great job producing the video. These topics are really hard to understand so material like this really helps!
Awesome video, it helps me understand the theme. More videos and growth to you
Thanks for the great video series. I am stuck at 6:01. The derivation seems not making sense. Could you elaborate?
Sorry, I got this now. But at 6:48, what is trial strain (equation)? And why is it equal to strain?
@@hschan9423 How you got the expression at 6:01 ?
It is amazing how much knowledge you hold 👏🏻
Thank you for your great video.
Can you provide reference to learn continuum mechanics to understand in detail

You can find the formulas in Dunne book.
what if in 2d condition, how the constitutive will be?

When will you upload the last part of this video?
