Mr. Clayton, the way you structure your lectures by illustrating every piece of theory with an example is a jewell in the land of education. I love it! The only negative point I can come up with is that you don't speak Dutch. Many greetings from the Netherlands.

I participated in a solid mechanics course when I was an undergraduate student in 2014. Actually, the first and second lectures remind me of ten years ago at school. I have been working as a CFD engineer since 2019 in the industry, but I am also trying to learn FEM because there are not as many job opportunities for CFD professionals. These lectures are actually ingenious and very helpful in expanding my career path. Thanks a lot.

Hi, I will be pursuing a master's course with having specialization in CFD. If possible can we have a discussion about that somewhere else?

Shouldn't it be (h/4) instead of (h/2) for the argument in the second set of parentheses at the 2:34:16 mark? Also, nice work...I'm loving these videos!

There is a minor error in the equation for von Mises stress: I2(s) is equal to 0.5{[I1(s)]^2 - I1(SS)} it doesn't affect the final result since I1(S) is zero

1:57:04 Hello, dear professor In slide displacement function, why is y not a function of x2? I see that when we move in the direction of x2, the value of y changes

At 1:07:10, is the I_1(S) missing the squared? I mean, I_2(S) = 0.5 * [I_1(S)^2 * I_1(S * S)], right?

At 43:20, how do we know which direction does each sigma_{i, j} point? For sigma_11, it points negative-e1. sigma_12 points positive-e2, sigma_13 points negative-e3. For sigma_31, it goes negative-e1. sigma_32 goes negative-e2, sigma_33 goes negative-e3. What is the rule here? Please help.

There is mistake in the direction of S12. Everything should be going in the negative ei direction. Thank you for pointing this out as I have yet to catch it!

The tetrahedron is formed by slicing a parallelepiped along an arbitrary plane. So, the force acting on the cutting plane is the reaction exerted by the other half of the parallelepiped and has an opposite sign. So basically, on all the faces besides the cutting plane, the stress vector would be the opposite sign. That is the only rule. And yes sigma12 would be in the negative direction.
