From Stacking Sequences to Ply Layouts: An Algorithm to Design Manufacturable Composite Structures
The problem of computing the ply layouts (engineering plies) of a composite structure from the definition of the stacking sequences of the zones is presented. These stacking sequences result from the design of the composite structure and they are considered to be admissible with respect to standard composite design and the manufacturing rules. We show that the definition of blended stacking sequences does not necessarily lead to a possible solution for the ply layouts. Therefore, the design process of a composite structure must include a further step after computing the stacking sequences which is to compute the ply layouts. We present an algorithm to compute a ply layout solution for a given set of stacking sequences. Using a backtracking approach, it efficiently checks all the possible ply layout combinations to find a solution. Some numerical experiments are presented to study the mapping between stacking sequences and ply layouts and the existence of a ply layout solution.
