Is there any range of cohesion values for coarse-grained soils?

I am working on cohesion and friction angle of different types of soils. The shear strength of coarse-grained soils are different from that of fine-grained soils.

I was wondering how two non-linear equations can be compared in terms of goodness of fit?

I am currently working with 2 non-linear equations; One is with 3 coefficients; The other is with 4 coefficients; I have used EXCEL SOLVER to minimise the sum of squared normalised residuals. I am...

How to define and get results (stresses) for certain points of a model in abaqus, using python? When the size of the model changes?

I want to do a parameter study of a aixsymmetric cylinder in Abaqus. I want to create several jobs where I get the stresses for 3 different points in my model. These points are defined. I wrote a...
