This is Fig. 20 of the 1999 addsoln paper. This slide shows normalized (Nx, Nxy) load-interaction curves for a composite, 4-layered angle-ply ([+ANG, -ANG, +ANG, -ANG]total) cylindrical panel with radius, r = 6 inches, length, a = 12.5 inches, arc-width, b = 3 inches, and total thickness, t = 0.04 inches. The layup angle, ANG = 45 degrees.
The "0.95xalternative" model (small circles) is much more accurate than the closed form "PANDA-type" model (small squares), but requires much more computer time.
