Get strain-stress relationship in spherical coordinates with Poisson ratio?

GROUPS:

Hello everyone,

I am wondering if there is a way to get the relationship between strain and stress in spherical coordinates with Poisson's ratio. I read the documentation here:

https://reference.wolfram.com/applications/structural/GoverningEquationsofElasticity.html

but there is only the relationship between strain and stress in spherical coordinates with Lamè's coefficients.

Thank you very much for your time.

Why not use "replace the Lamé coefficients with Young's modulus and Poisson's ratio " In[65] $\lambda -> - \frac{\nu E_c}{(1+\nu)(2\nu -1)}$, $\mu -> \frac {E_c}{2(1+\nu)}$?
