Abstract
Benchmark stacking sequence configurations with up to 21 plies are presented for laminates with properties similar to conventional materials, and against which new forms of coupled laminate behavior can be assessed. The benchmark configurations include fully uncoupled Extensionally Isotropic Laminates and Fully Isotropic Laminates, together with a special class of uncoupled laminate, possessing matching elastic properties in both extension and bending; more commonly referred to as a Quasi-Homogeneous Orthotropic Laminate. The concept of an Equivalent Isotropic Laminate is also introduced as a universally applicable datum; useful for characterization of ply number groupings for which no benchmark configurations exist. The vast majority of the benchmark configurations are found to possess non-symmetric stacking sequences, which also serves to demonstrate that stacking sequence symmetry is neither sufficient nor necessary for fully uncoupled laminate designs. Finally, dimensionless parameters are provided for each stacking sequence, from which the ABD matrix is shown to be readily derived.
