# Strain-stress relationship in spherical coordinates with Poisson's ratio [closed]

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.

• See the function ConvertCoefficients in section 7.2.6 "Elasticity Coefficients" in the source you gave... – Henrik Schumacher May 26 '18 at 9:34
