What is Polar Stress in Biharmonic Equation about?

This document discusses stress and strain relationships in polar/cylindrical coordinates. It contains: 1) Equilibrium equations for static equilibrium in polar coordinates considering stresses on an infinitesimal element in r, θ, and z directions. 2) Strain-displacement relationships showing how radial, tangential, and shear strains are related to displacements u, v, and w in polar coordinates. 3) Normal strains εrr, εθθ, εzz and shear strains εrθ, εθz, εzr are defined in terms of displacements and the
