This video and surrounding playlist (Structural Dynamics) is infinitely more informative than all the structural dynamics courses I took in university combined. Thank you so much for your clear, comprehensive explanations.

Happy to see you're still making videos!

I wish there was a good sharing of this video so that every student who has struggles in this field could overcome. This video is so helpful specially for me as a phd student working on the fracture mechanics. Thanks 🙏🏼🙏🏼🙏🏼

Kindly make a video on phase field model for cracking in brittle material and how we do the discretization of weak form. I am doing research on it and have a lot of difficulties in it.

Amazing sir, you are back.
By the way can you tell the aap you use to write?

Hey freeball!
Thanks. You are amazing!

Love your videos. Can you do some videos about PDEs?

Thank you, please kindly note that the units of "w(0)" and "w_, x(0)" are different and it is more approperiate to set them equal to zero seperately.

Very elegant. However the thing that has always kept me at unease is the intuition behind the expression of total potential energy. The contribution of strain energy term is understandable. The addition of load potential (potential due to external loads) seems kinda unintuitive. All the souces I have seen so far just define the total potential energy to be so. Hope you see this comment and respond to this query. Thank you

Thank you for this video. where can i find the proof for wich the boundary conditions go to zero independently? Is there a reference book for this?

Probably because you brought the differential under the integral when you calculated de variation. But I wonder why the strong form gives exact solutions and the weak one appropriate solutions.

divσ+ ρ=0 is the governing equation of my variational method… what is the nature and origin of a governing equation. What is it saying to us?
