The effect of ε33 must be incorporated since ε33 does not appear in these equations by using the (σ33 = 0) equation. This gives: ε33 = f(εαβ) Also, particularly in composites, another “notation” will be used in the case of plane stress in place of engineering notation: subscript x = 1 = L (longitudinal)…along major axis change y = 2 = T (transverse)…along minor axis The other important “extreme” model is… B.
