A composite ply with the properties listed below is used to construct multiple composite laminates. The thickness of the ply is 0.1 mm. The composite laminates are configured as 1) [0,90,0,90,0,90,0,90] 2) [+30,0]s 3) [45,-45,45,-45,-45,45,-45,45] a) Find the matrices A,B,D for the three laminates b) Which laminate has no normal-flexural coupling? c) Which laminate is the closest to be isotropic? Explain your answer. d) If the laminates are subjected to a unit strain along the x-axis while the rest of the strains and curvatures are zero (i.e. -1.4-,-k,-k,-k-o) sketch the stress σ, distribution for each of the laminate. e) The third laminate is used as a cantilver beam like shown below. Im P what is the maximum P that can be applied such that the maximum stresses at the top suface doesnot cause failure (based on maximum stress theory) The properties of the ply used in this problem are below E₁160 GPa, E = 10 GPa, Giz=7 GPa, V₁2=0.3 FIT 1800 MPa, Fic=1400 MPa, F2r=40 MPa, Fzc230 MPa, F6100 Mpa
