Question 6 A laminate is made of 4 carbon/epoxy plies with the lay-up given by stacking sequence [0°/45°/-45°/90°) as illustrated in Figure Q6. Each of the plies has the same thickness of 0.5 mm. The material properties for each of the plies are E1=140 GPa, E2 = 10 GPa, G12 = 6 GPa, V12=0.28. (a) Determine the ply reduced stiffness matrix [Q] for each ply in material axis system [2 marks] (b) Determine the transformed reduced stiffness matrix [] for each ply in reference axis system [8 marks] (c) Determine the [A], , [D] matrices for the laminate [15 marks] 2441 у 90° -45° x 450 0° 0.5 mm Figure Q6
