Stacking sequence of the laminated CFRP Specimen Z33 (from the same source as the previous 3 slides)

From the same paper as the previous 3 images.

Properties of the Specimen Z33:
Radius of the cylindrical shell, r = 250 mm.
Length of the shell, L = 510 mm
Total thickness of the wall = 1.25 mm

Properties of a unidiirectional ply:
E1 = 123550 MPa
E2 = 8708 MPa
nu12 = 0.32
G12 - 5695 MPa
Ply thickness = 0.125 mm

The next two slides show load-end-shortening curves and shell deformations of uniformly end-shortened Specimen Z33 as perfect (text slide) and with the measured imperfection shown previously (two slides hence).
