Ok, moderators say I am not allowed to add the formula to your answer. I'll add another answer.

Excellent! Biot Consolidation is the thing for me (at least in at this point). I'll edit the equation to your answer for future reference if you don't mind.

Could you tell more about the link? Its not working and the address suggests that it is a paper?

comment Euler angle rotation - active/passive
In this case the rotation around $Z'$ is $R_zP$. Your mathematics is correct but your are rotating your axis and your point (blue box). Rotate only the point.

In other words, the second rotation $R_z R_y P$ is a rotation respect to $Z$, not $Z'$

comment Euler angle rotation - active/passive
@YugT yes the outcome of the rotation will be different in the figures and then it matches the calculation. That is the essential thing here. Do not change the axis what you use for rotation. Now, the rotation between figures 2 and 3 is $R_z (-1, 4,0)$. You want $R_z (-0.707, 4, -0.707)$. (Alternatively you can drop the $R_y$ in the bullet 2 in the text).

@leonbloy: ok, good point. I change the answer a bit to be more correct.
