Hello everyone,
In vertical wellbore in anisotropic conditions in saturated rock.
Immediately after drilling, what would be excess pore pressure?
Would it be positive around the hole?
Why its not zero?
would it be negative?
Or its dependent on sign of mean strength increment Delta P?
Why would...
Hello everyone,
For critical Sate soil mechanics
Whats the status of critical state line? Is it always above or below the NCL?
Whats the reason for its being above or below?
If Initial condiiton of a volume of a granular material is above Critical state line and the material
is then sheared in...
Hello everyone,
Considering Modified Cam Clay Model.
Is the flow rate associated?
Whats the nature of strains? Are they elasto plastic?
The yield surface is described by an eclipse and therefore plastic strain increment vector
(which is normal to yield surface) for the largest value of the...

Hello everyone,
I have a question. When we have a
Vertical Wellbore & Anisotropic conditions and rock is saturated.

Hydrostatic compression Tests:
Hello everyone,
In Hydrostatic compression Test:
Stress invariants are P'=q=0. Whats the reason behind it?
In [ q p'] space the effective stress path is represented by a vertical straight line which coincies with q-axis. Why and whats its reason
and application...
For Mohr Coulomb yielding criterion.
If flow rate is associated, dilation angle is equal to the friction angle?
If we associate the flow rule, What is the orientation of verctor representing orientation of plastic strain.
Why is it not always vertical?
If the flowrate is associated, whats the...
Weakness plane model:
Hello everyone,
I have a question regarding Weakness plane model.What are limits of it?
Can it be only applied when Beta W = 45 ' + Theta w ' /2?
When does maximum possible strength predicted by this model occurs?
Is it at Beta w= 45 degree + Thetaw'/2?
When does this...
Dear all,
I have a question regarding Uniaxial compression test.
What is the mode of fracture in uniaxial compression test?
Is it local tensile fracture that is predominantly parallel to applied stress?
Could it also happen in case of nmacroscopic shear fracture.
Why is it not dependent...
Skempton Coefficients:
A & B are determined by Triaxial CID test. Whats the reason? of doing that?
Can B be determined by hydrostatic compression in undrained conditions?
Can A be determined by hydostatic compression in undrained conditions?
Whats the reason for not doing it or doing it?
Can...
Dear all,
I have a question regarding Oedometric compression test.
When is failure expected to occur in an oedometric compression test.
Is it when vertical effective stress reaches pre consolidation stress?
What would be stress invariants for oedometric test and what is their physical...
