This video is part of a series of videos on continuum mechanics (see playlist: • Continuum Mechanics .
The strain tensor is a mathematical construct to quantify the deformation of matter in continuum mechanics. But the formula for the strain tensor looks unintuitive at a first glance. In this video, the (small or infinitesimal) strain tensor is introduced, and its formula is explained.
Keywords: continuum mechanics, solid mechanics, fluid mechanics, partial differential equations, boundary value problems, linear elasticity, small strain elasticity, infinitesimal strain elasticity, kinematics

Hi, in this video I use the gradient of the displacement without much elaboration. Would you be interested in a video on gradient, divergence and rotation of fields?

Oh go on then

Absolutely.

Keep going on! Perfect explanations with great visualizations. I stuck at large deformations (differential geometry, tangent spaces), I hope you touch them in future, too.

of course!

Keep making videos man. Slowly your channel will get 1 M subscriber within a year.

Thank you so much! ❤️

Good explanation. Good topic. Good animations. Overall an excellent video. Please also cover computational fluid dynamics topics also in some of your videos.

High quality stuff you putting out here. Nailing the animations and the concept flow. Would love to see more from you.

Superb videos! thanks a lot. Keep it up!

@jimpal5119 2 месяца назад

Excellent explanation and visuals! Would love a video covering any nonlinear topic!

@ComputationalModelingExpert 2 месяца назад

Thanks a lot! :) More videos on nonlinear continuum mechanics are planned. I find nonlinear CM very interesting but it was hard to understand when I saw it the first time ...

i love how your videos always leave me smarter than before!

A beauty to behold. Keep us posted the algorithim will definitely make you blow up

I'm learning about tensors in AI, and tensors have been making my mind mush for a few days. Visual aids really help, even when the physics is a bit over my head. Nice video!

Thanks!

It's notable that (A + A^T)/2 is always diagonalisible.

@ComputationalModelingExpert Месяц назад

May be addressed in a future video :)

@Bledy49 Месяц назад

Great video, what's your background?

@ComputationalModelingExpert Месяц назад

Thanks! I studied computational engineering and did my PhD in computational mechanics :)

@elshons1576 2 месяца назад

Can you do a video about finite strain and why is defined as the difference of squares of two infinitesimal line segments?

@ComputationalModelingExpert 2 месяца назад

I want to do a video about finite strain and the different strain measures. Stay tuned :)

@shivamrajput6368 2 месяца назад

Thankyou for visualising this concept using animation…. I am currently working on large deformation, can you please suggest me some related resources.

@ComputationalModelingExpert 2 месяца назад

I worked a lot with "Nonlinear Solid Mechanics" by Gerhard Holzapfel, but I find it a bit too detailed for a beginner. Let me know if you come across a more didactic explanation. I would be very interested! :)

Very Nice channel

Thanks! :)

@imaginarynumber416 7 дней назад

Hi could you make a video about the material and spatial coordinates with intuitive explanation?

@ComputationalModelingExpert 7 дней назад

Hey, it's definitely planned, but unfortunately not in the immediate future, because I want to finish other videos first. Stay tuned and thanks for your patience :)

@hamzazaheer3783 3 месяца назад

Thanks for your Videos. I am fresh graduate in mechanical engineer (BS). I want to get into computational simulation especially multiscale modelling of composite. Right now i am learning continuum mechanics and FEA (Basic Concept). Do you have any advice for me ?

@ComputationalModelingExpert 3 месяца назад

Sounds great! 💪If you want to learn multiscale modeling, check out these unsurpassable lecture notes by Dennis Kochmann: ethz.ch/content/dam/ethz/special-interest/mavt/mechanical-systems/mm-dam/documents/Notes/CompMultMod_Notes.pdf

@@ComputationalModelingExpert Thanks for your help . Can't wait to see your upcoming videos.
