whenever κm≤κTf. Whenever κm≥κTf, the bounds defined by (4.193) should be reversed.
4.10.2 Axial Young’s Modulus
The bounds for the axial Young’s modulus are given by
(4.194)
which are valid only if μTf≥μm, and the bounds are reversed if μTf≤μm.
4.10.3 Axial Poisson’s Ratio
The bounds for the axial Poisson’s ratio are given by
(4.195)
which are valid only if (νAf−νm)(kTf−kTm)(μtf−μm)≥0, and the bounds are reversed if (νAf−νm)(kTf−kTm)(μtf−μm)≤0.
