So,

so that's how low

so oh

so that's wrong

And we also have the tension dice

where we can see the thrust and normal tension in different directions on the dice.

I can play around a bit and change the tension a bit.

For example

here we have 0

update and ok.

That's not so good.

Ok

he should update it across the board.

Obviously he doesn't want to

but it should be a demonstration.

And what we can do is

we can rotate the cut directions.

When we rotate the cut directions

he updates the cut sizes accordingly.

And we can also say, align with principal direction.

Now we are in principal direction.

He shows us

relative to the global coordinate system

where we are in principal direction.

And then we see here

current stress tensor 5

minus 1.

That would be our tensors in the main axis transformation.

We can now forget about the tractions.

But basically

we can look at the tension tensor

what happens when we start rotating the directions.

I think the update will have something to do with the new Matlab version.

But at least it works pretty well in principal direction.

I can rotate the tension tensor

see the cut sizes and see how it looks in the Morse tension circle.

Or at which points of the Morse tension circle we are.

Numerical inaccuracies not taken into account.

I think this makes the whole thing a little more appealing

when you can play around a little bit.

And then see what it is about with the tensors.

Just download it.

It should all have a Matlab license from the university.

You can just play around a little bit at home with it.

Otherwise

for today we will look at what...

We started the general description of elasticity a little bit last time.

We will continue there.
