Abstract
A method of configuring a composite laminate may include selecting at least two different material systems for the laminate. Each one of the material systems may have material properties and corresponding material invariants. The laminate may be comprised of a stack of plies having a stacking sequence. The method may include characterizing the stacking sequence using lamination parameters for each material system. The method may further include calculating a transverse shear stiffness of the laminate using the material invariants and the lamination parameters.
