Consider a 45 - 45s laminate with the material properties

Question

Consider a [+45/ - 45]S laminate with the material properties of Exercise 6.10. Compute the middle-surface strain ∈⁰_x, ∈⁰_y, γ⁰xy and the curvatures κ_x, κ_y, κ_xy for the following load cases

(a) N_x = 1000 N/m; all remaining components are equal to zero

(b) M_xy = 1 Nm/m; all remaining components are equal to zero

(c) Comment on the coupling effects observed.
