Figure 4
Representation glyphs of the unit-strain tensor surface corresponding to (a) thermal expansion at 240 K (after Fortes et al., 2008), (b) compressibility at zero pressure and (c) compressibility at 900 MPa. Black arrows indicate the orthogonal reference frame [cf. Equation (3) and Fig. 5a]. Coloured arrows show the eigenvectors of the Eulerian infinitesimal unit-strain tensor. Representation surfaces created using WinTensor (Kaminski, 2004). |
