Problem $2.$

Cylindrical pressure vessel. Consider an isotropic $($parameters $,)$ thick$-$walled cylinder with inner and outer radii a and $b,$ respectively. The cylinder is subject to an internal pressure $p_i$ and an external pressure $p_0.$ Determine the displacement and stress fields in the cylinder.
