I'll edit in my comments below:

Under section 1.2 specifically :

I don't have a problem with the definition given. An abstract definition is appropriate, since Fx is used for the general theory of equilibrium. However, it should be $x$ component, not X component.

Also seems fine as given. However, it should be $y$ component, not Y component.

$a$ comes from StolleGuo2008. $a$ is a constant that ensures the denominator in the calculation of $K_t$ is not zero and $K_t >> k_t$.

At least in the short term, I do not really want to support the documentation of the rigid finite element method in SSP. We don't want to put too much work into these aspects of the documentation.

$A$ is also defined in StolleGuo2008. As I mentioned above, we don't want to put too much work into the rigid finite element portion of the documentation. You can say that A is a material property related to the interface stiffness in tension.

C1_i is the shear force at the interslice interface for slice i.

C2_i is the normal force at the interslice interface for slice i.

Does kappa even appear in the current documentation? The parameter $A$ mentioned above is calculated from kappa (StolleAndGuo2008), but I don't think this equation is given in the document.

"Moment of a Body: assumed 2D allowing a scalar" isn't the best description. It isn't the moment of a body, but the moment of a force. I think we can just say "Moment of a force about a given axis".

Yes, please make this change and check the Drasil version as well.

Undefined/misdefined instances:

Yes, is should be c'.

Use c' instead

Can you put this in a separate issue. The theoretical model for Mohr Coloumb should be investigated.

This is the same phi as in the Mohr-Coloumb constitutive equation. There is just the possibility of a different friction angle for each slice.

Yes, this should be the specific weight of the water. Replace any occurences of wat with w.

Other:

Yes, good idea. Please do that.

@smiths You mentioned that "we don't want to put too much work into the rigid finite element portion of the documentation" with respect to the symbols a and A that came from StolleGuo2008. Would it be beneficial to leave the descriptions as FIXMEs then, to serve as a reminder that SSP needs to be updated in this regard?

smiths commented 6 years ago

Yes, I am fine with the FIXMEs. There is a reasonable chance that we will remove mention of a and A completely, at least temporarily.

(1 more point left to close this issue)


Re: Kappa is in the document: image image

It is in the same equation A is in, so are they close enough in nature for kappa to also be left as a Fixme that will be removed with a and A? @smiths

smiths commented 6 years ago

Yes, make kappa a fix me. Thank you.

niazim3 commented 6 years ago

Since lowercase kappa is a fixme, all symbols originally mentioned have been discussed/updated.
