INVARIANT PROPERTIES OF COMPOSITE MATERIALS

reportActive / Technical Report | Accession Number: AD0668761 | Open PDF

Abstract:

Invariant properties of the elastic coefficient matrices of laminated composite plates are presented. The use of these invariants in materials evaluation and design optimization is discussed. Simple formulas, based upon micromechanics results, are derived for the invariants in terms of constituent material properties.
