Figure 2
The local Cartesian coordinate system used in calculation of [\varepsilon_{zz}^{\,\rm{h}}]. The coordinate system is rotated about the z-axis by an angle [varphi], keeping the [x']-axis parallel with the radial component r of the original cylindrical coordinates. The grey square represents a cube of infinitesimal size for which the rotated compliance matrix [S^{\,\prime}] is computed.  [article HTML]
