Design variables used for optimization by PANDA2 of a laminated composite ring and stringer stiffened cylindrical shell under combined loads, Nx and N

This is Table 7 from the 2002 stagsunit paper. This table lists the design variables used in the optimization of ring and stringer stiffened laminated composite cylindrical shells under combined axial compression Nx and in-plane shear loading Nxy. (See the next slide)

The shells are optimized for two separate environments, that is, two different combinations of Nx and Nxy,
