Question

Exercise 6.18 Given ϵ0
x = ϵ0
y = γ0
xy = 0 and κx = 1.0 m−1, κy = 0.5 m−1, κxy = 0.25 m−1,
compute the strains (in laminate coordinates) at z = −1.27 mm in the laminate of Exercise
6.7.

Exercise 6.7 Find σ1, σ2, and σ6 at z = 0, on both laminae of a laminate [±30]T subject
to Nx = 1 N/m (all remaining forces and moments equal to zero), with t1 = t2 = 1.27 mm,
E1 = 137.8 GPa, E2 = 9.6 GPa, G12 = 5.2 GPa, ν12 = 0.3.
