”en, by inversion of Equation 12.20, for example, we can note that the following global strains

w y
w x y
, , , , , ∂ ∂

∂ ∂ ∂
are constant in the area under consideration. From this, the local strains of Equation 12.12 depend only on the z-coordinate in the laminate. ”is is the same for the membrane stress values σx, σy, τxy.
