Consider a [+45/ - 45]S laminate with the material properties of Exercise 6.10. Compute the middle-surface strain ∈0x, ∈0y, γ0xy and the curvatures κx, κy, κxy for the following load cases
(a) Nx = 1000 N/m; all remaining components are equal to zero
(b) Mxy = 1 Nm/m; all remaining components are equal to zero
(c) Comment on the coupling effects observed.
