The Young modulus Y = 4 μ ( μ + λ ) 2 μ + λ ( 11 , 12 ) naturally arises upon recasting (up to boundary terms) the free energy in Eq. In certain cases, the plane stress model can be used in the analysis of gently curved surfaces. For example, consider a thin-walled cylinder subjected to an axial compressive load uniformly distributed along its rim, and filled with a pressurized fluid. The internal pressure will generate a reactive hoop stress on the wall, a normal tensile stress directed perpendicular to the cylinder axis and tangential to its surface. The cylinder can be conceptually unrolled and analyzed as a flat thi… ordinary v qualified tax dividends
