Rotating a 6x6 matrix 3

[sartorbjk]

Hello,
I have a matrix called compliance matrix (6x6) in 3d-stress space.
It looks like:
x y z 0 0 0
x1 y1 z1 0 0 0
x2 y2 z2 0 0 0
0 0 0 a 0 0
0 0 0 0 b 0
0 0 0 0 0 c

I want to make a rotation. I should turn X axis 45° towards y-axis.

My question is, how can I form my 6x6 rotation matrix? Is there an already implemented code in excel?
I really appreciate your help.


Best Regards,

Thanks IDS. Have made the changes now.

kacarrol: i previously checked the first file you sent. I compared the results with the one that I got from software. It did not match.
In short, I will check your second file to give a feedback with more details.

I would go straight to checking the third one. I know the second one is wrong.

@kacarrol:
Sorry for the late reply. I did not have time to go over your document. However, I found something which I believe, would be helpful for you as well.

I hope it helps you to see if your excel files are working or not (at least in terms of formulation)
