1. A method for efficient design of a specified laminated composite material having tensor properties, composed of a set of candidate materials having tensor properties, each of the candidate materials having a thickness or thickness fraction, stacking sequence, and layup angle to be determined, comprising the following steps:

  • Calculating tensor invariants of the specified laminated composite material, Calculating tensor invariants of the candidate materials, Forming a set of relationships between the tensor invariants of the specified laminated composite material and the tensor invariants of the candidate materials, Determining from the set of relationships an optimal set of candidate materials, thicknesses or thickness fractions, stacking sequence, and layup angles.
