Starting with the out-of-plane shear constitutive equation (II.1.28) and of the expression defining the out-of-plane shear force vectors one makes developments similar to those of section II.1.7.1 and defines the following quantities:
They are used in the expression:
(II.1.68) |
Correspondingly, one estimates the laminate out-of-plane shear CTE vectors:
(II.1.69) |
(II.1.70) |
These two expressions allow to write the expression of the inverse of (II.1.68):
